Metallica bassist Robert Trujillo remembered the important role Ozzy Osbourne played in his life and career in a new tribute to the late musician.

He also credited Osbourne for being the reason the supergroup Infectious Grooves was able to tour in 1991. "We weren’t ready to hit the road, but he made us step up and make it happen," Trujillo wrote, adding that they opened for Osbourne's Theater of Madness tour.

Black Sabbath, members of Metallica and a handful of other rockers paid their respects to the legendary Ozzy Osbourne at his funeral yesterday (July 30).
