Every Wednesday night, head to The Haven for a Hootenanny—an open mic night of live, raw, high-energy music from performers around the city. Get your fix of folk in Jamaica Plain from 9:30pm-12:00am and try one of the delicious Haven burgers with a beer for just $15 after 10:00pm. The featured artist changes each week, but first-timers are welcome to show up and strut their stuff, too. Call 617.524.2836 for more information.
