Turning 50 next spring, Tool vocalist Maynard James Keenan announced a special birthday bash to mark the occasion. Taking place at LA's Greek Theatre on May 10, the party will see Maynard performing with two of his side-projects - Puscifer and A Perfect Circle. As Spin reports, recently reunited art-rockers Failure are also included on the bill as a special b-day request from Keenan himself. "Making it to the half century mark can be equal parts daunting and relieving. 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," Keenan said. "This was the perfect opportunity to tick off one of my bucket list items in the form of a Failure reunion. What better birthday present could one ever hope for?" Tickets are scheduled to go on sale starting December 6, VIP packages will be available a day earlier. More info available here. These days, Maynard is mostly preoccupied with the new Tool album. However, his other bands aren't exactly falling behind either - Puscifer unleashed their new EP "Donkey Punch the Night" back in February, while A Perfect Circle released "Three Sixty" hits compilation on November 19. So Maynard will be 50 soon - make sure to share a few birthday wishes in advance in the comment section.
