The Long Island thrashers in Extinction A.D. — which is essentially hardcore greats This is Hell with a new guitarist (Ian Cimaglia) — are injecting their tried and true punk formula with a healthy dose of shredding. The band's latest record, this year's "Decimation Treaty," is a brutal, no-nonsense crossover-thrash offering that marries hardcore's seriousness with thrash's penchant for the extravagant. Leave it to a bunch of hardcore lifers to make two genres that too often slide into self-parody sound dangerous again.
Extinction A.D. will perform with Darkest Hour, Whores, Murder in Rue Morgue, and A Silent Ending on Saturday, February 24, at Photo City Improv, 543 Atlantic Avenue. 6 p.m. $20. facebook.com/photocityimprovcomedyclub; facebook.com/extinctionAD.
