The Chocolate Church Arts Center, 804 Washington St.,  Bath, welcomes Patty Larkin to its main stage at 7:30 p.m. Friday, Oct. 2. The Boston-based artist developed into a guitar virtuoso after studying jazz at the acclaimed Berklee College of Music. She’s experimented with live track looping and even dipped her toe into hip-hop. But at her essence, Larkin is a singer-songwriter, spawned from the 1970s movement that brought Joni Mitchell and Richard Thompson to popular culture. Larkin redefines the boundaries of folk-urban pop music with her inventive guitar wizardry and uncompromising vocals and lyrics. Tickets are $18 in advance/$22 at the door and available online www.chocolatechurcharts.org or by calling the box office 207-442-8455.
