A separate statement shared on the band's website Feb. 5 said "a lifetime of legendarily aggressive performing has taken its toll on Dee Snider's body and soul." It revealed that Snider has been suffering from degenerative arthritis, and he's had multiple surgeries to perform.
"Adding insult to injury, Dee has recently found out the level of intensity he has dedicated to his life's work has taken its toll on his heart as well," the statement continued. "He can no longer push the boundaries of rock 'n' roll fury like he has done for decades. Says Snider, 'I don't know of any other way to rock. The idea of slowing down is unacceptable to me. I'd rather walk away than be a shadow of my former self.'"

Twisted Sister first formed in the early 1970s, with Snider joining in 1976, bringing his talents as a vocalist and songwriter. Their first album with a major record company was released in 1983, but it was their 1984 album, "Stay Hungry" that made the band a household name.

When speaking with Fox News Digital in June 2024, Snider discussed the hard times after the band broke up, saying he "lost everything."
"Double bankruptcy, my career collapsed," he said. "I was riding a bicycle to a desk job, answering phones. I was married, had three kids. You know, things just went incredibly south.
