Colorado thrash metal band Havok blasted into Lubbock metal fans' ears Friday night at the 37th FMX Birthday Bash -- and their ears are still ringing today.

Havok has been opening for The Killthrax Tour, featuring Killswitch Engage and Anthrax. And for anyone at the Birthday Bash unfamiliar with these guys, we have no doubt they walked out the Lone Star Pavilion as fans. What's not to like?

Insane drums? ✅
