Stevie Wonder, Jay-Z Juice Bonnaroo

Stevie Wonder galvanized Bonnaroo last night with a sweaty, irresistible nighttime performance, an act that headliner Jay-Z followed with torrid, flawless bombast, writes the AP. The two took the Bonnaroo main stage in succession, pumping the festival crowd—some 75,000 in total—full of energy. The day's acts also included Weezer, Jack White's the Dead Weather, Norah Jones, and a middle-of-the-night set by the jam band Disco Biscuits.

Excessive heat in the high 90s has been a constant at this year's ninth annual Bonnaroo. Reprieve came late in the afternoon when a passing shower cooled things off. Conan O'Brien has been emceeing the Bonnaroo main stage and twice performed his "Legally Prohibited from Being Funny on Television" comedy show. World Cup fever also came to Bonnaroo, where the US-England match, which finished with a 1-1 draw, was broadcast on a big screen. (More Bonnaroo stories.)
