In death metal, few bands have earned as much lasting influence as Long Island’s Suffocation. Over the course of ten albums, the band led the class in turn-on-a-dime song complexity and production that gave each instrument brutal clarity. If Suffocation doesn’t sound quite as innovative now as it did in the ’90s, that’s because so many other bands followed their path. This tour is the last for vocalist Frank Mullen, who will leave guitarist Terrance Hobbs as the group’s sole original member. Cattle Decapitation — a worthy headliner on its own — heads up support. The band’s machine-gun delivery makes the best of singer Travis Ryan’s almost superhuman ability to switch between gutteral growls and eerie screeches. Krisiun and Visceral Disgorge open.
