Last night was just your normal, garden-variety Phoenix headlining show at Madison Square Garden. And then Daft Punk showed up to crash the party. (You know, the usual. No big deal.) The duo started performing "Harder, Better, Faster, Stronger," which eventually morphed into Phoenix's hit "1901." The following video captures the suspense and delerious crowd response. Daft Punk's soundtrack to Tron Legacy is due out on December 6. Phoenix's August show at the Pageant was excellent, but sans French robots.
