Put on your dingiest flannel shirt, tear a few holes in your jeans and prepare to be transported back to the early ’90s as Metz and Bully co-headline an evening at the Metro. In 2015, both acts released albums that served as nods to the distorted guitars and throat-scratching vocals of the grunge era. Hell, Metz is signed to Nirvana's label (Sub Pop) and Bully cut its LP (to tape) at Steve Albini's Electrical Audio. Rumbling post-hardcore outfit Slow Mass gets the party started. This show is part of the Tomorrow Never Knows festival.
