These days, Helmet is pretty much Page Hamilton's baby. The frontman/guitar virtuoso has remained the lone constant over numerous changes to the legendary metal group's lineup, including a breakup in 1999 (during which Hamilton's new band toured with David Bowie) and a partial reunion in 2004. Helmet's sound has evolved since the 1992 release of the seminal album Meantime: the impossibly dense, staccato guitars and elaborate time signatures have given way to more spacious arrangements and more conventional (albeit enormous) metal riffs. Starting off the night are Mondo Generator (former Queens of the Stone Age bassist Nick Oliveri's band) and fellow LA metalheads Fireball Ministry and Vyrus.
