A league ahead of the regular troupe of tribute acts, UNAUTHORIZED OZZY not only featured the self proclaimed "greatest Ozzy impersonator on Earth" in Peter Marrino, a man noteworthy enough for having fronted LE MANS and CACOPHONY, but also a former OZZY OSBOURNE band member, NIGHT RANGER guitarist BRAD GILLIS. The band tracked live recordings at a 28th August 2004 gig at the Boulder Station Casino in Las Vegas.
