Maynard James Keenan's 50th birthday isn't until April of next year, but the multitalented rocker has already got the day planned. On May 10, 2014, Keenan will celebrate his half-century on Earth by performing with both A Perfect Circle and Puscifer in Los Angeles. Adding to the excitement, L.A. alternative rock band Failure, who recently announced plans to reunite, will also play the celebration.

What better way to celebrate a birthday than to perform at the legendary Greek Theatre? Maynard Keenan famously fronts Tool, A Perfect Circle and Puscifer, and the vocalist will be performing with two of those acts at the birthday event, which is sure to bring in a packed house.

“Making it to the half century mark can be equal parts daunting and relieving,” says Keenan. “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.”

At the request of Keenan, Failure, whose lineup includes former A Perfect Circle guitarist Troy Van Leeuwen, will come together for the reunion show. “This was the perfect opportunity to tick off one of my bucket list items in the form of a Failure reunion," Keenan raves. "What better birthday present could one ever hope for?”
