Tommy Clufetos (born December 30, 1979) is an American session drummer most noted for his work with Black Sabbath during their Black Sabbath Reunion Tour, which highlighted their new album 13.
He also toured with them on their final tour. He is also the drummer for Black Sabbath vocalist Ozzy Osbourne.
Clufetos started playing drums at age seven and went on to join Mitch Ryder and the Detroit Wheels (1999) before joining forces with Ted Nugent (2001-2003). He played on Craveman and Love Grenade. After Ted Nugent, Tommy went on to join Alice Cooper's Band for his 2004 tour. He also performed on Alice Cooper's 2004 release Dirty Diamonds. He went on to join Rob Zombie from 2005 to 2010, and played on Zombie's 2006 album Educated Horses, on Zombie's first live release, 2007's Zombie Live, and on 2010s Hellbilly Deluxe 2.
In May 2012 Clufetos played with Black Sabbath, filling in for original drummer Bill Ward. However, he did not perform on their album 13, as Brad Wilk ended up behind the kit during the sessions. Clufetos returned to Sabbath in April 2013 for their North American tour, starting in Houston on July 25, 2013. Clufetos continued with Sabbath in 2014 with the first show at the Barclays Center in Brooklyn, New York, and the final show at Hyde Park, London.
