The singer for Tool, A Perfect Circle and Puscifer is throwing a special Cinquanta birthday concert in honor of his 50th year. Keenan has announced he’ll take the stage with two of his bands, A Perfect Circle and Puscifer, May 10 at The Greek Theatre in Los Angeles.

“Making it to the half century mark can be equal parts daunting and relieving,” Keenan said in a statement. “I figured I would remove the sting of officially being referred to as ‘Gramps’ by throwing a party and outlasting all of my rude friends.”

The event will also offer a reunion performance by the group Failure, which is extra special for Keenan. The group features Troy Dean Van Leeuwen, who played guitar in A Perfect Circle before joining Queens of the Stone Age in 2003.

“This was the perfect opportunity to tick off one of my bucket list items in the form of a Failure reunion,” Keenan said. “What better birthday present could one ever hope for?”
