1986 to 1995: Ozzy Osbourne, Y&T, White Lion, Suicidal Tendencies and MD.45
DeGrasso originally auditioned for Ozzy Osbourne and played on the demos of The Ultimate Sin before Ozzy and Bob Daisley had a fallout and Ozzy chose to replace the entire band except for Jake E. Lee.[citation needed] DeGrasso then joined the veteran metal band Y&T in 1986, replacing their original drummer Leonard Haze. He remained with the group into the 1990s. In 1991, he briefly filled in as White Lion's touring drummer when Greg D'Angelo left the band.[2] He went on to play with Suicidal Tendencies to replace R.J. Herrera from 1992 to 1995, releasing a studio album with the band in 1994, and on Megadeth's Dave Mustaine's side project band, MD.45, in 1995.
1998 to 2002: Megadeth
In 1998, Mustaine asked him to join Megadeth to replace Nick Menza as drummer and continue the band's Cryptic Writings tour. He was asked to play with Megadeth five days before the next show. He walked around with a walkman all day to memorize the songs. DeGrasso recorded and toured behind Megadeth's Risk album in 1999–2000, The World Needs a Hero in 2000–2001, and was featured on Megadeth's first ever live CD and DVD release, Rude Awakening, which was released in 2002.
2002 to 2008: Stone Sour, Ronnie Montrose, David Lee Roth Band, and Ministry
DeGrasso has performed at the Modern Drummer Festival in 2002, Ultimate Drummers Weekend in Australia, Drummer Live in the United Kingdom, and toured with Stone Sour (Slipknot vocalist Corey Taylor's side project), and with guitar legend Ronnie Montrose. DeGrasso played with The David Lee Roth Band in 2006 and joined Ministry on their 2008 tour.[citation needed]
2008 to 2012: Alice Cooper Band, F5, and Dokken
In late 2008, DeGrasso came back to Alice Cooper's band to fill in for Eric Singer while Singer played a few KISS shows in the U.S. DeGrasso has also been the full-time drummer for heavy metal band F5 and Hail (along with ex-Megadeth bassist David Ellefson). In summer 2012, DeGrasso toured with Dokken, filling in for Mick Brown, who left Dokken to tour with Ted Nugent.
In early 2014, DeGrasso filled in for Bobby Blotzer in Ratt and played with them on the Monsters of Rock cruise. DeGrasso is the first drummer to have filled in for Blotzer, since he joined the band in 1982. He filled in for Blotzer again on the Monsters of Rock Cruise in October 2016 before becoming the band's official touring drummer in 2017. He left Ratt in June 2017[citation needed]
