MainstageWhen I saw The Mars Volta at EndFest 2007, the band walked off the stage early, with frontman Cedric Bixler-Zavala explaining that someone had thrown urine at the band. During today’s set, we discovered why: he’s the kind of guy who should be showered in piss. Consider the evidence:– During the first song, he picked up the drummer’s ride cymbal and stand and chucked it into the audience. (In junior high, I observed such a combo fall off a table and crack a kid’s head open.)– He later tossed an electric fan into the audience.– He then tried to take a videographer’s camera away from him, in front of the stage.– When he couldn’t get the video camera, he turned his attention to SW PHOTOGRAPHER RENEE MCMAHON and TRIED TO TAKE HER CAMERA AWAY FROM HER. I have to wonder: What would it have taken to have the plug pulled on these clowns? I ask you, Live Nation brass, what had to be hurled into your ticket-paying audience’s face to make this happen? A guitar? An amp? Where’s freshly bottled urine when you need it!?
