12 Awesome Lollapalooza 2010 Moments

Lady Gaga expresses her animalistic side while crowd surfing during the Semi Precious Weapons' Lollapalooza show on Aug. 6.

With more than 150 acts spread across its eight stages, Lollapalooza 2010 was a long, loud, always entertaining - and at times, historical - weekend for dozens of reasons. Here's 12 videos, shot by the fans themselves, that'll make you wish you'd been there.

Green Day Gets Fans Into the Act

During the two-and-a-half hours that the Bay Area's favorite sons rocked Lolla's main stage on Saturday, the trio had no problem sharing the spotlight with a few very lucky fans. During 'KnowYour Enemy,' Billie Joe called a flag-waving boy onstage and coerced him to stage dive into the photo pit. Later, a little girl joined the band center stage and sweetly pretended to be knocked unconscious by a booming pyrotechnic. Then Billie Joe called yet another fan onstage to sing lead vocals on their slacker hit "Longview." And we're pretty sure they all had the time of their lives.

The Return of the Strokes

America waited ages to see it, but the the Strokes finally brought their reunion show Stateside on Friday night and rocked Chi-town with an onslaught of gritty New York garage-rock riffs. Wearing black leather and sunglasses at night, eternally cool frontman Julian Casablancas led the quintet through a potent set of tunes from their three acclaimed albums. The band played barely an hour, but the intensity of the set made the Strokes' return one of the weekend's most talked about performances.

Cut Copy, Hot Chip, Chromeo Keep It Funky

Guitars definitely dominated the Lollapalooza lineup, but sprinkled amongst the multitude of bands who wanted fans to rock out were a few party-starting groups who brought the rave. Among them were Australia's Cut Copy, who got hands waving and feet moving on Saturday afternoon, and London's Hot Chip who warmed up the Friday masses for a blazing sunset set by Montreal electrofunk duo Chromeo.

Edward Sharpe & the Magnetic Zeroes Call for a Sit Down

Fans scaled tress to get a glimpse of Edward Sharpe & the Magnetic Zeroes, who played to a jam-packed crowd on Lollapalooza's Sony Bloggie stage Saturday afternoon. The Los Angeles group drew one of the festival's biggest audiences and stunned the crowd with waves of sound propelled by tambourines, horns, accordion, piano and guitars. The performance was already feeling like the weekend's most intimate, but frontman Alex Ebert got even more personal with the fans at the set's conclusion. After asking the audience to sit down -- not an easy feat, considering the lack of space -- he wandered into the audience and performed the song 'Brother.' The scene instantly became the stuff of Lollapalooza legend.

Erykah Badu's Soulful Seduction

In true diva fashion, Ms. Badu came to the stage 17 minutes late, throwing off Lollapalooza's otherwise clockwork schedule. But her throng of fans didn't seem to mind. Sporting a towering blonde mohawk and earrings that dangled down her face, it didn't take long for Erykah to have the crowd eating out of her caressing hand. Whether she was tinkering with a drum machine, crooning a bluesy ballad or dropping raw hip-hop funk from the stage, all eyes and ears stayed fixed on the diminutive singer whose smooth, seductive soul chilled out the masses under the blazing summer sun.

Empire of the Sun Makes a Dazzling Debut

While rock music dominated most Lollapalooza stages, Perry's dance area kept the beats pumping all weekend with a host of top-notch DJ talents. But things got live on Saturday evening when Australia's Empire of the Sun took the stage for their first-ever U.S. show. The Cirque du Soleil-on-ecstasy extravaganza featured chilly synth-pop tunes, a quartet of costumed dancers, and ear-to-ear smiles from the grooving crowd under the trees.

Arcade Fire's Epic Conclusion

While the Soundgarden grunge revival was happening to the south, Montreal's Arcade Fire was enrapturing ears on the north field of Grant Park with swelling, swooning indie-pop anthems. Tunes from the band's latest album 'The Suburbs' were greeting enthusiastically, but the crowd sang the wordless refrains of older hits like "Rebellion" and "Wake Up" with an almost religious, unifying zeal. The vibe was so thick when the lights came up, that after three days of non-stop heat and endless port-a-potty lines, no one wanted to leave the grounds. This, ladies and gentlemen, is how you end a festival.
