Twisted Sister’s Dee Snider shared a post on his official Twitter page to remember the band’s iconic drummer A.J Pero, who passed away on March 20, 2015.

Like almost every other band, Twisted Sister went through a couple of lineup changes before settling with their classic lineup Jay Jay French, Eddie’ Fingers’ Ojeda, Dee Snider, A. J. Pero., and Mark ‘The Animal’ Mendoza. A.J. Pero joined the band in 1982 and left in 1986 to venture off performing with other bands.

He returned to the band in 1997 for their reunion and stayed with them until he passed away from a heart attack in 2015. He was on tour with Adrenaline Mob and sleeping on the tour bus. The band members weren’t able to wake him up the next day. A year after the heartbreaking incident, Twisted Sister disbanded.

Seven years had passed since the drummer’s death on March 20, and Dee Snider gave him a tribute in his recent tweet. He stated that he missed his late bandmate’s smile the most and made his fans emotional. A fan also wrote how much of an idol he is, to which Snider replied by stating how underrated he is as Pero was frustrated by his simple drum parts with Twisted Sister.

Here is what Snider initially tweeted:

“7 years ago, my friend & Twisted Sister drummer A. J. Pero died. The thing I miss most (besides his incredible drumming) is his smile. We would be in the thick of it, he’d be pounding away, and when I looked back, he would give me a smile that said, ‘This is what I love!'”

A fan tweeted his tribute:

“On 20/03/2015, the rock world lost one of its own, the incredibly talented and underrated drummer of Twisted Sister A.J. Pero. He was one of my drumming idols growing up. He had so much ability and played with heart and soul.”

Snider’s reply follows:

So underrated. The man could play anything. He studied as a child with Gene Krupa & toured Europe at 12 with a swing band as Little Anthony Pero! I frustrated him by making him play so simply with Twisted Sister, but how many can say they created a drum opening everyone knows?!”
