Twisted Sister has lost a dear brother.
A.J. Pero died today after apparently suffering a heart attack, according to the band. He was 55.
The drummer had been on tour with heavy metal group Adrenaline Mob, which he would play with in between Twisted Sister gigs. He was found unresponsive by fellow Adrenaline Mob members this morning on their tour bus.
"The members of Twisted Sister are profoundly saddened to announce the untimely passing of our brother, AJ Pero," the band said in a statement on its Facebook page. "The band, crew and most importantly the family of AJ Pero thank you for your thoughts and prayers at this time."
