HARRISON — New England Celtic Arts in collaboration with Deertrees Theatre will present a very special night with three of the region’s master songwriters Wednesday, July 6. Curtain is at 7:30.

The Master Songwriters concert will commemorate the 80th anniversary of Deertrees Theatre at 156 Deertrees Road in Harrison.

The Theater will launch its Celtic Roots/Traditional concert series with Denny Breau, Heather Pierson and Emilia Dahlin performing in the round. This event is the launch of the fourth year of collaboration between Deertrees and New England Celtic Arts.

Breau’s rhythmically flawless and dazzlingly clear style allows him to do amazing things with a six-string guitar. He first draws in an audience with a finely arranged melody and then slides effortlessly into scorching finger-work that sets ears aflame. The lightning-fast guitar lines that seem almost humanly impossible to accomplish are balanced with those that have a quiet intimacy and wrap tenderly around his carefully crafted songs. He mixes genres with ease — folk, Delta blues, country and jazz — “creating a totally accessible musical mélange that captivates as it entertains,” according to Lucky Clark writing for the Kennebec Journal.

Pierson is an award-winning pianist, multi-genre singer/songwriter, arranger, bandleader and performer. From New Orleans-style jazz and blues to rousing Americana and poignant folk narratives, Pierson’s memorable, intimate and cathartic live performances, both solo and with her acoustic trio (Davy Sturtevant on strings/cornet and Shawn Nadeau on bass), feature her virtuosity on piano, her bell-tone vocals and her commanding yet playful stage presence while wielding a tenor banjo, melodica or acoustic guitar. Her music moves seamlessly and effortlessly from one style to the next, and a growing catalog of wildly divergent CD releases reflects her boundless creativity.

Born on a small farm south of Boston to a musical instrument collecting father and accordion playing mother, Dahlin was destined for a life of music. She started piano, formally, at the age of 5 and trained classically for the next 13 years. It was Christmas Day 1996 when she decided she wanted to play the guitar. She went up to the attic, pulled out a warped and worn guitar that once belonged to her great-grandfather, and started to play. She never stopped. Now, wielding a voice that defies the size of her body and strong storytelling sensibilities, Dahlin has carved out her name as a unique songstress. She weaves mesmerizing tales (complete with Greek myths, robotic messiahs, epic floods, and tax evaders) with raw, rootsy folk and dynamic jazz vocals. Her well-crafted songs sound as if they’ve been left outside where time and weather have worn cracks for the wind to whip through. Her sky-rocketing energy is delivered with honesty.
