Fifteen fans were taken to hospital during TOOL's performance at the Street Scene festival in San Diego, California on Saturday (05AUG06). The crush happened when fans of the band rushed forward at the start of their set - the final performance of the event. Frontman Maynard James Keenan yelled to the crowd after the band's second song, "Step back so you don't get trampled. It's just rock," reports MTV News. According to organisers, none of the injuries were life-threatening.
