The front man for the band Of Mice & Men, Austin Carlile, announced Friday that he has left the band because of health issues.
"It's with heavy hearts that we announce Austin's departure from the band for reasons pertaining to his health," the band wrote in a Facebook post.
Carlile has struggled with Marfan syndrome, a connective tissue disorder, which has caused him significant pain while touring.
"After his most recent series of surgeries at Stanford University Hospital, following the cancellation of our European headlining tour, his team of doctors informed him of the damage that performing, & more specifically his aggressive vocals, have been causing his body," the band explained in its statement.
In his own letter, Carlile said he's suffered multiple spinal tears, which have caused him "violent pain" every time he performs.
Carlile's doctors warned that his screaming vocal style could eventually cause "permanent and irrevocable damage" to his spinal cord and nervous system.
"After learning this I realized that I had to step away from Of Mice & Men, no longer able to scream most of our old material, or continue to scream on anything new. I cannot continue on," he explained in a letter posted to the band's Facebook page.
The four remaining members of the band will continue to perform and intend to play their scheduled European tour dates this summer.
As for Carlile, he has moved to Costa Rica to rest but said he will continue playing music.
"I am still able to sing and I'm hungry for what is next to come even though I have no idea what that may be," Carlile wrote.
