Rachel Sumner, previously known as co-founder of Boston bluegrass band, Twisted Pine, has been creeping away from that genre, and from any one genre for that matter. She’s a singer, songwriter, multi-instrumentalist (guitar, banjo, flute, clarinet, + more) working on recording her first full length album, ‘Heartless Things,’ an album that hovers somewhere between chamber-pop, indie-folk, Americana, and the blues.
