Twisted Sister's A.J. passed away back in March 20, 2015 of a heart attack at the age of 55. Pero was scheduled to perform with his band Adrenaline Mob in Poughkeepsie at The Chance that night. He died at Vassar Brothers Hospital.

I got to meet A.J. over the years at many Twisted Sister concerts and also got the chance to work with him with the annual Biker’s for Babies March of Dimes motorcycle events back in the day. He was such a nice guy and I’m very saddened by this news. I recall djing at an area bar one night when A.J. showed up and hung out with everyone. He signed autographs and took pictures with everybody. He was a real class act. He had joined the band Adrenaline Mob in 2014 as replacement for drummer Mike Portnoy and was also a member of the band Four By Fate.

On June 13, 2015 Twisted Sister payed tribute to A.J. with a special concert at Starland Ballroom in Sayerville NJ. Check out video below.
