SPIN: "at the Canyons Resort, a semicircle of immense buildings so high up they’re accessible by ski lift, about 2,000 Utahans have already shivered through sets by Jet and Good Charlotte. They are here because they’ve won a contest, something to do with Pepsi caps and free iTunes downloads, but when Green Day charge out of the wings — to the theme from 2001: A Space Odyssey — the fans cheer like they have won a contest again. After tearing into “American Idiot,” Armstrong announces, “Hey, fuck Pepsi and fuck everything else — this is a fucking Green Day show right now.” But the set’s most indelibly punk-rock moment comes later during a cover of Operation Ivy’s “Knowledge,” when Armstrong, Dirnt, and Cool ask for volunteers to take over on guitar, bass, and drums. Out of a fevered stage rush, they pluck three kids, who, after quick tutorials, bash their way through the song with enthusiasm if not precision. Armstrong shows his stand-in how to close strong with a flying leap off the monitor. The kid jumps high enough that, were he on a skateboard, he would easily clear a parking meter — and for as long as he’s in the air, he’s a rock star, too."
