Albert Hammond's surprise appearance on Late Night with Jimmy Fallon earlier this week provided one of the cooler Christmas-related moments on network television in recent memory. Yes, it sounds as if they wrote this song about five minutes before they went on stage, but Julian Casablancas and The Roots sound really great together, and the entire experiment reinforces the message that the difference between a Christmas carol and a Christmas rock song is a bitchin' rhythm section. I love the way that ?uestlove's drum kicks in from off-screen before you know the Roots are even involved, and as the camera pans to the main stage you can all but hear the audience thinking "wait, who does that sound like . . . that's the guy from The Strokes!" Its not the most ambitious Christmas special I've seen, but a surprisingly effective one nonetheless.
