It's a Treasure Island Music Festival free-for-all, and we're ready to rock and/or dance overboard with the all-star line-up at the gonzo weekend-long sonic blast. In the name of rockers, Sonic Reducer faces off against the dance-floor repping Super Ego over French electro-pop juggernaut Justice, headlining Saturday. What has the stylish duo wrought? Plus: we also look at TV on the Radio, Goldfrapp, Hot Chip, Vampire Weekend, prep school rock, and other artists appearing Sat/20-Sun/21. For the complete fest schedule and details, go to www.treasureislandfestival.com and dig for gold.
