Texas thrash veterans GAMMACIDE are bringing their toxic assault to Pennsylvania this September, with the band scheduled to appear Friday, Sept. 11, at Shiloh American Legion Post 791 in York as part of a Raptor Rise Collective-presented show.

The Pennsylvania stop arrives at a particularly important moment for GAMMACIDE. Sept. 11 is also the scheduled CD release date for Toxic Mercenaries, the band’s first full-length collection of new material in more than 35 years. The eight-track album is being released through NoLifeTilMetal Records, with vinyl editions scheduled to follow Oct. 30. (Roxx Records)

GAMMACIDE resurfaced in earnest in 2025 after decades of sporadic activity, reuniting around original members Varnam Ponville, Rick Perry and Scott Shelby and once again taking its notoriously abrasive Texas thrash to the stage. The band originally emerged from the Dallas-Fort Worth metal underground in the late 1980s, releasing Victims of Science in 1990 and developing a cult following for its combination of breakneck riffing, violent rhythmic attack and lyrical fixation on radiation, environmental collapse and biological catastrophe.

The comeback moved into another gear this summer with “Overload,” GAMMACIDE’s first newly released music since the band’s early-1990s dissolution. Released in July, the track serves as the opening shot from Toxic Mercenaries and retains the hostile, high-velocity character that made Victims of Science an underground thrash favorite. GAMMACIDE has also confirmed an East Coast run around the new record, including additional September appearances. (Gammacide)

The York show takes place at Shiloh American Legion Post 791, 1490 Poplars Road, York, Pennsylvania, with doors opening at 7 p.m. The event is all ages, with attendees required to be 21 or older to drink. Advance admission is $18, increasing to $22 at the door.

For Pennsylvania thrash fans, this is considerably more than another touring date. GAMMACIDE arrives in York on the same day its first new album in more than three decades officially lands, putting the band’s return to active duty — new record, new material and all — directly on a Pennsylvania stage.
