The following band descriptions come from Nateva Festival organizers:

7 Walkers featuring Grateful Dead co-founder Bill Kreutzmann – 7 Walkers, is a new project featuring famed drummer and Grateful Dead co-founder Bill Kreutzmann, guitar master Papa Mali, legendary New Orleans bass man George Porter Jr. (The Meters, Funky Meters) and multi-instrumentalist Matt Hubbard (Willie Nelson, Fastball). Jambase says the band’s recently released self-titled album “is the most organic, original music to come out of the core Grateful Dead alumni since the passing of Jerry Garcia … 7 Walkers goes for the creative jugular in such a lusty, exuberant manner. “

Gregg Allman Band – An acclaimed guitarist, vocalist, and songwriter, Rock and Roll Hall of Famer Gregg Allman of the legendary Allman Brothers Band carries on the rocking with the Gregg Allman Band. Following brother Duane’s tragic death in 1971, Gregg became the driving force of the powerful 1970s Southern-style rock-n-roll the Allman Brothers defined for a generation. The Gregg Allman Band, in all its forms, with its groovy, bluesy, and R&B influences, brings Gregg Allman and his fans back to their roots. Gregg is known as a gifted natural interpreter of the blues, with a soulful and distinctive voice that has become one of the defining sounds in the history of American music.

Big Head Todd & The Monsters – With a sound that is part classic rock, part bluegrass, with a little R&B thrown in for good measure, Big Head Todd & The Monsters began rocking the Rockies 25 years ago. Founded in 1986 by Todd Mohr, Rob Squires, and Brian Nevin while studying at the University of Colorado, Big Head Todd and The Monsters began touring the Mountain and Pacific time zones and quickly gained a devoted following for their live act. They’ve played such famed venues as the Fillmore and Red Rocks.

John Butler Trio – Hailing from down under, The John Butler Trio has rocked stages worldwide including Red Rocks in Colorado and the NYC Summer Stage in Central Park. Their music has been categorized under variations of bluegrass and sunshine, and was called “gritty and adventurous” by the Austin Chronicle. Infusions of Celtic sounds and steel drums set the John Butler Trio apart from fellow folksy indie rockers and simultaneously make them irresistible. The ever-evolving John Butler Trio is Australia’s most successful independent artist in recorded history.

Karl Denson’s Tiny Universe – Karl Denson was a member of Lenny Kravitz’s band for five years, has collaborated with Fred Wesley’s band, and as a trio with Miles Davis alumni Dave Holland and Jack DeJohnette. Eventually Karl Denson’s unique, individual style began to solidify, and is his own amalgamation of jazz, funk, R&B, hip-hop, rock, Afrobeat; anything that naturally makes people want to move. As KDTU, the band has performed in festivals across the globe including Bonnaroo, The New Orleans Jazz and Heritage Festival, Monterey Jazz Festival, Newport Jazz Festival, the Fuji Rock Festival in Japan, North Sea Jazz festival in Holland, Moscow Jazz Festival in Russia, East Coast Blues and Roots Festival in Australia and the Montreux Jazz festival in Switzerland.

Donna the Buffalo – Over the past 21 years, Donna the Buffalo, hailing from upstate New York, has crafted an eclectic breed of musical Americana. Rock, folk, reggae, country, and Cajun/zydeco influences pervade the sounds of Appalachia, flushed out with lyrical social commentary. The group is Tara Nevins, Jeb Puryear, Dave McCracken, Kyle Spark and Vic Stafford. Their devoted following dons the self-titled moniker “The Herd,” making Donna the Buffalo an inarguably American musical experience.

EOTO – Bringing a love of the unscripted together with a passion for electronic dance music, throbbing bass, and thudding beats, Michael Travis and Jason Hann synergize years of percussion experience with musical acts as diverse as Youssou N’Dour, Dr. Dre, and the String Cheese Incident. EOTO is 100% improvised dubstep/breakbeat/house/drum and bass/trip-hop dependent on audience energy to overcome the barrier between stage and floor, creating a unique show every single time. Even their studio recordings are single-take improvisation, allowing mood, ambience, and vibe to entirely dictate musical creation.

Eskmo – Connecticut native but San Fransisco-based Brendan Angelides is an electronic music producer who records and performs live as Eskmo. Defying classification, his work belies a wide range of influences and a long career in a rapidly-changing musical environment. Introduced in the mid-90s to acts such as Primus and The Prodigy, his craft continued to develop from there. His first official creation was for a high school graduation project, and has continued to release albums and perform live, always absorbing contemporary musical and cultural shifts. The name Eskmo was inspired by The Residents’ 1979 album Eskimo, and he has been Eskmo since 1999.

Ghostland Observatory – Building on a beat-driven love of rock, friends Aaron Behrens and Thomas Turner collaborated in a studio in Austin, Texas, and the result is Ghostland Observatory. A little bit 80s synch-pop, a little bit 70s psych-rock, and a little bit 90s everything, Ghostland Observatory is the inevitable culmination of the last several decades. Their music can only be described as BALLSY. Their debut album, delete.delete.i.eat.meat… was released in 2004. They’ve played Lollapalooza, Bonnaroo, Coachella and Austin City Limits.

Guster – Ever since the band’s humble beginnings at Tufts University, Guster has always sought to outdo itself. The band founded the eco-friendly Campus Consciousness Tour using buses powered by biodiesel and performances powered by wind power. Past performances include a sold-out NYC Radio City Music Hall performance, a Boston Pops at Symphony Hall performance and a sold-out 33-date college tour.

Gypsy Tailwind – Portland, Maine’s own sweethearts of live performance, Gypsy Tailwind spins Americana music for foot-tappers and sawyers’ alike. Their influences, Emmylou Harris and Jackson Browne, are as diverse as classic and modern indie rock. Melodic and harmonious, Gypsy Tailwind’s music is both heart wrenching and heartwarming. They have opened for headliners such as Ray Lamontagne, John Fogerty, Rusted Root, and Guster, and are sell-out headliners for local Portland, Maine shows. Gypsy Tailwind is Amanda Gervasi, Dan Connor, Chris Dow, Colin Winsor, Tyler Stanley, and Max Cantlin.

Keller Williams – Self-described as self-indulgent (why would anyone like music he makes if he doesn’t like it?), the perennially unpredictable Keller Williams is simultaneously a one-man-band and a team player. He has collaborated with fellow artists on his albums and draws inspiration from a wide variety of genres, from new-age punk rock to jam bands to Colorado bluegrass. He collaborated with husband-and-wife duo Larry and Jenny Keels on his 15th album, Thief, made up entirely of bluegrass-ified covers of a vast array of artists including Amy Winehouse, the Butthole Surfers, and the Grateful Dead.

Dave Mason – A founding member of the post-invasion British psychedelic rock band Traffic, Dave Mason left the band after their second album. He began a solo career in the US in 1969 and performed on albums with The Rolling Stones, George Harrison, and Paul McCartney. Mason played acoustic guitar on the track All Along the Watchtower on Hendrix’s Electric Ladyland album, which became a Top 10 single in 1968 and was ranked 48th in Rolling Stone magazine’s 500 Greatest Songs of All Time. Mason joined Fleetwood Mac in the early 90s and toured with that band for two years. As a founding member of Traffic, Dave Mason was inducted into the Rock and Roll Hall of Fame in 2004.

Max Creek – A consummate 1970s jam band, Max Creek’s influence on later bands such as Phish is immediately apparent. In true jam band style, Max Creek’s live shows often last into the wee hours and their improvisational grooves bring the audience along for the ride. Their sound is reminiscent of contemporary The Grateful Dead, mixing bluegrass and rock into never-ending solo riffs. As a jam band, Max Creek has a large and dedicated following of its live show, making them an ideal festival participant.

McLovins – Rolling Stone describes The McLovins as “a trio of Connecticut kids who have managed to harness the musical ferocity of Trey Anastasio, Les Claypool, and Stewart Copeland before being able to legally drive a car.” This is not an exaggeration; the trio is made up of 16 and 17 year-olds from Connecticut, where the driving age is 18. Taking their band name from a character’s alter-ego in Superbad (the movie – McLovin, the “25–year-old organ donor from Hawaii”), The McLovins are how the next generation jams. The McLovins cultivate their fan-base through YouTube, Facebook, and of course, their live shows. The band has appeared at Nateva, Mountain Jam, StrangeCreek, and Gathering of the Vibes music festivals.

Moonalice – Moonalice strives to rekindle the glory days of hippiedom – musically and socially – through their no money, no problems, Hakuna Matata ideology. Moonalice is a self-described band of California hippie musicians, proud to boast no label, manager, or publicist. Dedicated to the fan experience and ahead of their time, Moonalice invented Twittercast concerts – which are free broadcasts to fans over social networks – and promote online downloading of their albums. As the band says, they “grew up with Elvis and practice freedom of speech every day.”

The New Deal – Like compatriots Arcade Fire, Rush, Neil Young and The Guess Who, Canadian band The New Deal can do no musical wrong. The New Deal has appeared at Bonnaroo, Langerado, The New Orleans Jazz Festival, Coachella, Street Scene in San Diego, Berkfest, Gathering of the Vibes, Camp Bisco, and the Detroit Electronic Music Festival. They blow minds on both sides of the border with their progressive “livetronica.”

New Riders of the Purple Sage – The history of New Riders of the Purple Sage reads like a who’s-who of the live music scene throughout the late 1960s and 1970s. NRPS evolved as an amalgam of everything great coming out of rock, bluegrass, psychedelic drugs, and jamming that characterized the era. The band got its start touring with the Grateful Dead, and throughout their tenure musicians came to NRPS from Jefferson Airplane and the Byrds. They’ve played with such infamous acts as Janis Joplin, The Band, and Sly Stone. Performances dwindled in the 80s and 90s, but NPRS still finds time to play the festival circuit.

Chris Robinson and Jackie Greene – Acoustic Duo – Chris Robinson is the lead vocalist for rock and roll’s The Black Crowes. He is also the front man of side project The Chris Robinson Band. Heartbreak-inducing crooner Jackie Greene is a 25-year-old singer and songwriter whose music crosses between folk, country, rock, jazz, and bluegrass. He has released four albums in his young career, each one distinct but fiercely reflective of his own voice. The Chris Robinson and Jackie Greene – Acoustic Duo project has never been heard, they will debut at Nateva.

Robert Randolph & the Family Band – Embracing the storied traditions of American music, from the influence of African-American music, Gospel and Christian blues, to the music that people working in fields across the south likely sang nearly a century ago. The band sees these as the real roots of rock and roll; all American genres – blues, rock, jazz – come from these roots. Robert Randolph and the Family Band is the exemplar of how the musical traditions of gospel, blues and rock can unite to tell a unique story of Americana. The band has collaborated with Leon Russell and Ben Harper and toured with Eric Clapton, Dave Matthews Band, B.B. King, The Roots, and John Mayer.

Tim Reynolds and TR3 – With a musical career spanning more than thirty-five years, guitarist and sonic innovator Tim Reynolds is known for his technical and improvisational skill in his craft. His repertoire includes jazz and blues, classical and reggae, funk and soul, and psychedelic and progressive rock. TR3 (Tim Reynolds Trio) is known for their fusion of funk, rock, and jazz. He toured with TR3 during the 1980s and 1990s, but the trio disbanded when Reynolds met Dave Matthews and they began their long-time collaborations. TR3 reunited in 2007 and Reynolds is currently the lead guitarist for DMB. Tim Reynolds is renowned as one of the most talented, emotional, and thoughtful musicians of our time.

Martin Sexton – “Modern-day troubadour” Martin Sexton is a prolific generator of pretense-free rock and roll. Soulful and rhythm-driven, like a true troubadour his music echoes real life and he shares his passion with his fans. He began playing the streets of Boston in the 1990s and has since won numerous awards, played at Bonnaroo, and opened for the Dave Matthews Band. He runs his own independent record label, Kitchen Table Records.

Edward Sharpe & The Magnetic Zeros – Edward Sharpe and the Magnetic Zeros will be headlining Saturday night. Their single “Home” and debut full-length album Up From Below became viral smash hits almost two years ago and are anthemic for an entire generation of indie-music-lovers. With slow-grooving, powerful beats, infectious lyrics, and influences drawn from across the globe, Edward Sharpe and the Magnetic Zeros seem to have written everybody’s theme song.

Trombone Shorty and Orleans Avenue – Troy Andrews, a.k.a. Trombone Shorty’s live performances have been called devastating and his high-energy, party-down intensity is legendary. Everything you’ve every heard about New Orleans – the good, the bad and the ugly – lives in Shorty’s music. He’ll be touring in support of his new album, Backatown (Verve Forecast April 20) described as a Supafunkrock, a mix of rock, funk, jazz, hip-hop and soul.

STS9 – Atlanta-born and California-based instrumental electronic rock band Sound Tribe Sector 9 (or STS9 for short) mesmerized Nateva’s audience last July with their audiovisual, culturally-infused musical spectacle. Ranked #25 on Pollstar’s list of top grossing touring acts, STS9 sells out shows, opens for Jay-Z, owns their own record label, and uses their power for good by raising money for their activism efforts. Idealists and visionaries, STS9 is the post-rock dance music love child of an electron cloud of funk, jazz, beats, psychedelics, and hip-hop.

Thievery Corporation – Thievery Corporation has been able to sell out the famed Hollywood Bowl, London’s Shepard’s Bush Empire, the Theatro Vrahon Melina Merkouri in Athens, Greece, and many other legendary venues around the world. Spreading their unique sound far and wide, the DJ duo consisting of Rob Garza and Eric Hilton were always great admirers and curators of dusty grooves and all but forgotten music styles. They borrow from the classically sensual and blunted sounds of their favorite Brazilian bossa nova, Jamaican dub reggae, vintage film soundtracks, Afrobeat, Latin and psychedelic rock to forge into new sonic territory.

Bob Weir of the Grateful Dead – Bob Weir began playing guitar at 13/14 (depending on source), influenced by local guitarist and Jefferson Airplane front-man Jorma Kaukonen, and at 16 joined forces with Jerry Garcia to form Mother McCree’s Uptown Jug Champions, then the Warlocks, which soon after (and thanks to Ken Kesey’s acid tests) became the Grateful Dead. Weir is lauded as one of rock’s finest and most distinctive rhythm guitarists, jamming for hours on end, as well as the co-genius behind much of the Dead’s finest lyricism. He currently plays with collaborative efforts RatDog and Furthur. His performance at Nateva is solo acoustic.

Peter Wolf – Best known as lead singer for the J. Geils Band, he has toured, collaborated, and performed with The Velvet Underground, Sun Ra, The Lovin’ Spoonful, The Young Rascals, The Byrds, The Shirelles, Mick Jagger, Keith Richards, Aretha Franklin, Carlos Santana, and Elvis Costello, among many others. During a stint as Boston station WBCN’s music and program director and late night DJ, the “Wolfa Goofa Mama Toofa,” he created a program that fused rare rock and roll with rhythm and blues, his own influences as an artist. The show became extremely popular with the general radio audience and as a resource for musicians in New England.
