Boston's experimental hard-rockers Milligram were formed in 1996 by ex-Only Living Witness vocalist Jonah Jenkins and guitarist Darryl Shepard, a one-time member of both hardcore band Slapshot and stoner rock outfit Roadsaw. Initially something of a side project for both of them, the band only became a going concern two years later when bassist Bob Maloney and drummer Zephan Courtney were drafted to record the P.C.-averse Hello Motherfucker debut.
