Query: Definitely 311

Thank you, 311, for putting the trippy stylings of "Transistor" behind you and moving back to what you're good at: music. "Soundsystem" grooves back to the 311 of old, filled with memories old and new, of "Music," "Grassroots," and "311." This is a solid album. You're a 311 fan? Buy it. If you aren't a fan, become one.
