We are devastated to report that Twisted Sister / Adrenaline Mob drummer A.J. Pero has died at the age of 55. The drummer reportedly passed away peacefully in his bunk on Adrenaline Mob's tour bus.

While Twisted Sister have performed with many drummers throughout the band's 43-year career, A.J. Pero was easily the band's most celebrated man behind the kit. Pero had many stints with Twisted Sister, the longest being his latest run of 12 straight years (2003 - 2015) with the heavy metal legends.

The drummer manned the kit for some of Twisted Sister's most legendary and timeless albums, such as Under the Blade, You Can't Stop Rock 'n' Roll and Stay Hungry. As for Adrenaline Mob, Pero took the place of former Dream Theater stickman Mike Portnoy, staying true to the project until Pero's untimely death.
