Dee Snider just unleashed a bitter rant about Twisted Sister drummer A.J. Pero's death -- saying his heart attack was totally avoidable, but Pero did nothing to save himself or protect his family.
Dee came on TMZ Live to talkTMZ Live to talk about the band's upcoming farewell tour, but ended up venting about Pero. Dee told us he's in the anger stage of grieving because ... he says Pero knew he had a history of heart disease in his family, but never got checked out.
A.J.'s autopsy results -- which Dee revealed -- are what really set him off about his friend's death.
Watch him unload ... he's a man on a mission.
In a business not known for fostering healthy and stable relationships, singer Dee Snider and his wife, Suzette, have somehow made their marriage work for 34 years and running, even as Dee traveled the world as a frontman in the glam metal band Twisted Sister. How have they survived the ups and downs and kept things fresh and interesting decades into their union? Watch the Video
A.J. Pero was laid to rest (3/26/15). We took this photo in 1985 after a shoot we did with his monster Ludwig drum kit for the "Come Out and Play" tour. I have been finding some classic photos of A.J. from back in the day. Here is a slide show I put together that I would like to share with his family and fans. - mark weiss
