The band announced the sad news on its Facebook page on Friday (March 20).
“The members of Twisted Sister are profoundly saddened to announce the untimely passing of our brother, AJ Pero,” the statement read. “The band, crew and most importantly the family of AJ Pero thank you for your thoughts and prayers at this time.”
AJ, pictured here with frontman Dee Snider, joined the band in 1982 and left in 1986, before returning again in 1997. He drummed on all but one albums released by the group.
We send out our thoughts and condolences to AJ‘s loved ones during this difficult time.
