New York death-metal band Suffocation have been around since 1988 (but for a break between ’98 and 2003) but this current tour is a bit special because it’s the last for vocalist Frank Mullen. The writing’s been on the wall for some time — the group has been using dual vocalists for a few years, and now Mullen has decided he’s ready to retire, at least from this group. He’ll be tough to replace; his low-pitched vocals were considered groundbreaking within the death-metal world back in the ’80s. But the noises are that Suffocation will soldier on, with longtime guitarist Terrance Hobbs leading the way. We trust that they’ll continue to be awesome, but this last chance to see them with Mullen should be grabbed. Cattle Decapitation, Krisiun, Visceral Disgorge, Insineratehymn and Festering Grave also play.
