Hard rock still has a reputation as music for meatheads in some corners, but these bands evolved the form by approaching it with sophistication and purpose. Deftones could be staggeringly heavy while toying with discordant chords and electronic atmospherics. Rage Against The Machine don’t smuggle politics into their music; the message is front and center, fueling them with justified anger. The set culminates with the Sonic-speed rush of “Through The Fire And Flames”; the song wasn’t actually written for a video game, but by the end, you’ll feel like you’ve collected a million rings.
