Many Boston musicians will play a benefit concert on June 27 at Harpers Ferry in Allston, MA. Proceeds for the event, billed as Jenefit, will go to Jenny Davis, a former employee at Gamelan Productions and the Berkshire Mountain Music Festival, who had to have her leg amputated after a Jeep struck her last October. The benefit line-up features Jiggle, Addison Groove Project, members of Uncle Sammy, Another Planet, Jon Trama, and Jon and Steve of Mighty Purple. There will be a minimum of donation of $10 requested at the door.
