Ozzy has left the building

Rock-based revues and tribute shows are biting the dust left and right, according to our LVA research staff. As the Riviera (whose workforce has been allegedly reduced by 60%) creeps toward the grave, Masters of Rock preceded it last Saturday, banging its last head. Over at Palace Station, Rock n’ Roll 2 Soul expired a fortnight back, making room for another imitation Coasters show. (Score: doo-wop 1, rock 0.) And, after being booted from the Wyrick Entertainment Complex (which itself has died and been resurrected as an extension of the V Theatre), Rockstar: The Tribute was announced for — and scrapped by — both the Riv and the Harmon Theatre, probably making it the only Vegas show to have the invidious distinction of closing before it ever opened … at least twice.
