A chant of "Alice! Alice! Alice!" went up into the blustery skies above Lollapalooza's vitaminwater stage on Friday afternoon, as thousands of soaking-wet fans awaited the arrival of fiery Crystal Castles frontwoman Alice Glass. Moments later Ethan Kath, the brains behind the Castles' video game-inspired dance attack, took the stage to thunderous applause, followed by Glass, dressed in her characteristic all-black (except for her white Converse), whose arrival sent the kids into a wet, muddy frenzy. As the Toronto natives tore through cuts from their self-titled debut album, including 'Air War' and crowd favorite 'Crimewave,' Glass tested the befuddled security staff's limits, climbing around scaffolding and onto speakers, plunging into the front of the crowd, and chugging from a bottle of Tito's Vodka.

One of Glass's forays into the crowd nearly got out of hand when a "fan" grabbed the singer in a very inappropriate way. But Glass wouldn't end up the victim. The diminutive singer threw a mean punch, shaking her hand in pain after making contact with the offender. Luckily one person wasn't enough to derail the show. After taking a quick drink, Glass proclaimed, "We're going to play one more despite him," and then, pointing to the hundreds of outstretched arms in the crowd, "All those hands are going to reach boobs on their own!" Then, during a momentary break from the rain, they launched into a scorching rendition of 'Courtship Dating' that included Glass dumping her vodka directly onto the screaming fans up front.
