A.J. Pero had been complaining of a sore arm for about a week, and had recently taken a few days off, according to agent Dan Stanton. Twisted Sister guitarist Jay Jay French said "Pero was found this morning...

in his tour bus. Pero was taken to a hospital in Poughkeepsie, New York where he later died of what is reported to be a Massive Heart Attack. Pero had been on tour with the band Adrenaline Mob when he suffered the Heart Attack. Pero was only 55, and is one of many great rockers we have lost in 2015.
