The mathcore and metalcore titles attributed to Converge never quite fit. If musical precision is a requirement for the former, and heavy, breakneck-paced riffing qualifies as the latter, then Black Flag deserves the same designations. Converge was started in the early '90s by a group of guys who didn't really bother to make a clear distinction between extreme musical styles. But it was 2001's Jane Doe that made a case for the band's pioneering a sound that appealed to listeners with a taste for high volume, aggressive music with incendiary lyrics and no distinct genre. You can hear Converge's influence in modern death metal, grindcore, hardcore and the like, but this Marquis show is a chance to decide for yourself what the band is about.
