System Of A Down frontman Serj Tankian ran into some vocal trouble while wrapping up a string of hometown dates last week, but the band was able to soldier on with help from some high-profile friends.A case of acute bronchitis had Tankian coughing up blood during the band's show last Saturday at Los Angeles' Troubadour, and the illness forced the singer to leave the stage. Not wanting to disappoint its hometown fans, the band enlisted the aid of a string of guest vocalists, including Kyuss' John Garcia, (hed) pe's M.C.U.D., and System guitarist Daron Malakian. Ozzy Osbourne's son Jack even got into the action, lending vocals to System's cover of "Snowblind," a classic from Ozzy's Black Sabbath days. The tactic appeared to work, as the club told the band that no one asked for a refund after the show. The gig marked the end of a sold-out three-night L.A. stand that saw the group hit the Whisky and the Roxy before rolling into the Troubadour. Tankian was taken to a nearby
hospital, and is expected to be fine by the time the band opens Black Sabbath's farewell shows in England later this month.In the meantime, the band still plans to shoot its next video in the coming weeks. The band will hook up with short filmmaker Charlie Deaux to shoot a clip for "Spiders," one that spokespeople for the band promise will have more narrative and will play out like a short story.
