At Festival 8 at the Empire Polo Club in Indio, California Saturday night, Phish, as promised, donned a musical Halloween costume and turned their second set into a top-to-bottom recreation of the Rolling Stones' rock 'n' roll classic, 'Exile On Main Street.' To help them with this lofty ambition, Phish employed a horn section with female vocals delivered by none other than the venerable Sharon Jones.

The band's choice was kept under wraps and narrowed down from a list of 99 classic albums, including works by David Bowie, Prince, Radiohead, Jimi Hendrix, the Rolling Stones, King Crimson and even young upstarts MGMT.

Great as it was to see Phish deliver an impeccable cover set of such an important album, the true champion of Festival 8 was Phish's third set of the night, when they returned to the stage to play their own material. They jammed, threw down, freaked out, and rocked a party hard while 80,000 flying glowsticks pulsed to the beat.

Afterwards, performance artists led willing participants through an ingenious, interactive, integrated 'Alice and Wonderland'-meets-haunted house creation known as 'The Coil.'

Phish kicked off Sunday by serving up coffee and figure-eight donuts to every concert fan as they perform a high-noon, first-ever acoustic set. And what kind of Phish festival would it be if it wasn't then followed up by, well, two more sets?
