Just when it seemed Saturday couldn't get any hotter, Sharon Jones and the Dap Kings took to Bonnaroo's Which stage, grooving and popping their way through an hour-long set that had even the stiffest fans shaking like there was no one looking.

Concord, North Carolina's Avett Brothers drew a massive (and especially rowdy) crowd to Bonnaroo's Other Tent Saturday, picking and stomping their punk-tinged bluegrass into the stratosphere and proving why they just may be one of the most underrated acts at this year's festival.

Brooklyn's Fiery Furnaces kicked their epic indie-pop into full gear Friday afternoon as dedicated fans began filtering into Bonnaroo's stage compound, amassing beneath the shade of That Tent and basking in the cool breeze that foreshadowed the rain to come.

Maybe it was the anticipation of waiting for half an hour, or maybe it was the booze...or maybe it was the opening song about booze, but whatever the reason, the Felice Brothers were greeted by thunderous applause and an already energized crowd Thursday night.

Brooklyn three-piece the Big Sleep wasted no time getting things going Thursday afternoon, kicking off their set, one of Bonnaroo's first, with a screeching intro that was the perfect precursor to the hour of chaotic, pounding psychedelia to come.

What? Taking cues from their larger-than-life Americana predecessors, namely Bob Dylan and Woody Guthrie, the Felice Brothers specialize in boozy, rambling tales of backwoods nostalgia told in rootsy piano, guitar, and drum renderings.
