Steve Cooper talks with bassist Rudy Sarzo. Rudy has held down the bottom end for some of the most beloved and successful acts in heavy metal history since the early 1980s. He was a member of Ozzy Osbourne's band beside renowned guitarist Randy Rhoads (which he chronicled in his best selling book Off the Rails.) He rejoined Quiet Riot in time for its smash album Metal Health and went on to work with Whitesnake, Dio and Queensryche, not to mention a 5-year stint with hard rock juggernauts Blue Oyster Cult.
