The Burren’s Sunday night “Back-room Acoustic Music” series, or “B.A.M” is a weekly residency on the best club sound stage in Somerville. This event promotes underground artists playing live original acoustic music.

Different artists from all around the town, all around the country and even all around the world are booked at 8 pm and 9 pm and the EmCee and host of the evening Tom Bianchi will take up his battered bass guitar and close out each Sunday night with a set of his own often joined by some of the music community's best artists.
