Drug abuse is not the reason, apparently...

MUDVAYNE have pulled out of the PLEDGE OF ALLEGIANCE tour, starring SLIPKNOT and SYSTEM OF A DOWN.

A spokesperson for the band was quoted on www.launch.com blaming “personal reasons”, and refuted drug abuse suggestions that have been circulating in the music industry.

Mudvayne will now form part of Ozzy Osbourne‘s A Night Of Merry Mayhem tour, featuring Rob Zombie and Soil, starting October 31 in Tucson, Arizona.
