Raising a ruckus

The last time we combined Rockstar Energy Drink, Jagermeister, and a trip to Hot Topic we ended up with a shaved head, a ton of gnarly tattoos, and a really bad attitude. Maybe that's how a lot of the guys playing on the Mayhem Fest - sponsored by those three companies - ended up in their metal bands. The show features the thrashy horror metal of Slipknot and the agro-power of modern-rock radio workhorses Disturbed, but we're more stoked about the howling, melodic screamo of Underoath and the doomy prog-metal of Mastodon. 1 p.m. $22.25 - $49.75.
