Quadstock featured pop-rock headliner Tokyo Police Club last year, but this year, SEAC is bringing the funk with hip-hop artist Del the Funky Homosapien.
Phantogram's unique dance-friendly sound has helped them play as opening acts for more established bands such as The Antlers, Metric, Minus The Bear and Zero 7.
Camp 10, Seattle University's resident reggae-heads will be playing the Quadstock student stage, returning after their recent Battle of the Bands appearance.
Tying together influences ranging from Radiohead, Red Hot Chili Peppers, Modest Mouse and Yeah Yeah Yeahs, The Brain Cooks craft a sound that's all their own.
