The self-described “hippie with soul,” Allen Stone got it spot on. His crunchy-granola look, accented by thick oversized frames, is totally reminiscent of Janis Joplin, “The Queen of Psychedelic Soul” herself. His voice is like a perfect chocolate candy bar—rich, milky, packed with sensual caramel gooeyness and surprising nougaty patches. *HEAVY BREATHING* Though I wouldn’t be surprised if this hippie with soul refuses to eat anything with a soul. With Maiah Manser. Triple Door, 216 Union St., 838-4333, thetripledoor.net. 6 p.m. SOLD OUT. All ages. DML
