The thunderous, precise engine behind Twisted Sister's glam-metal anthems, driving 'We're Not Gonna Take It' into rock history.
A.J. Pero's drumming wasn't just about keeping time; it was a relentless, powerful assault that defined the backbone of 1980s heavy metal. Born in New York City, he cut his teeth in the hard-driving club scene before joining Twisted Sister in 1982. His muscular, no-frills style provided the perfect foundation for the band's anthemic, fist-pumping sound on breakthrough albums like 'Stay Hungry.' Tracks like 'We're Not Gonna Take It' and 'I Wanna Rock' were propelled by his solid, pounding grooves, which cut through the makeup and costumes with pure rock force. Pero was the steady, powerful metronome at the heart of the band's chaotic, theatrical live shows. After Twisted Sister's initial dissolution, he remained active, lending his talents to bands like Adrenaline Mob and playing with classic rock acts like Cities. His sudden passing in 2015 shocked the metal community, which remembered him as a dedicated, powerhouse musician whose work was essential to an era.
