With a resume boasting Alice Cooper, Ozzy Osbourne, Suicidal Tendencies, Lita Ford and Y&T, Jimmy DeGrasso was also the mega-powered, driving force behind one of hard rock's most revered outfits of all time, the multi-platinum, Megadeth.

Jimmy moved from Pennsylvania, to the bustling musical Mecca of Los Angeles more than a decade ago. " I moved to L.A. hoping that someone like Ozzy would be looking for a drummer, and lo' and behold, I landed the gig with Ozzy playing on the Ultimate Sin album" says DeGrasso. Though the Ozzy gig was short lived, Jimmy spent three years with the critically acclaimed Y&T, before leaving the band in 1990. The skate-punk flavored, Suicidal Tendencies followed in 1992 as well doing a ‘fill–in’ tour with Alice in Chains in 1993. DeGrasso then toured the world with Alice Cooper from 1995 to 1998, played on the Fistful of Alice album in 1996 and returned to Alice briefly in 2001. Jimmy played on Dave Mustaine’s (Megadeth Vocalist/Guitarist) solo album, MD-45 in 1995 and then received a call back from Mustaine, in 1998, to join Megadeth as a permanent member and continue the bands’ Cryptic Writings Tour. DeGrasso recorded and toured behind Megadeth’s Risk album in 1999-2000, The World Needs A Hero in 2000-2001 and was featured on Megadeths’ first ever live CD and DVD offering, Rude Awakening in 2002.

Since the demise of Megadeth, Jimmy has performed at the prestigious Modern Drummer Festival in 2002, Ultimate Drummers Weekend in Australia, Drummer Live in the UK and toured with Stonesour, Marty Friedman, guitar legend Ronnie Montrose, David Lee Roth and Alice Cooper.

Most recently Jimmy has recorded a CD entitled ‘The Reckoning’ with the band F5 along with his old friend David Ellefson. In 2008 Jimmy toured the world performing drum clinics in support of Pearl Drums, Sabian Cymbals, Evans drum heads and Promark drumsticks. Also introduced were Jimmy’s Signature snare drum by Pearl Drums and his signature 23” Over-Ride Cymbal by Sabian.

In 2013, Jimmy was invited to join the new band Black Star Riders featuring much of the current lineup of Thin Lizzy. They recorded their first album "All Hell Breaks Loose" in January 2013 with producer Kevin Shirley.

He played with Ratt at the Monsters of Rock Cruise in October 2016 before becoming official touring drummer in 2017.
