After kicking off their winter 2012 North American tour with a pair of weekend gigs in East Rutherford, N.J., the Dave Matthews Band stuck around around the New York City area for an appearance last night (Dec. 3) on 'Late Night With Jimmy Fallon.'

Not only did DMB perform the 'Away from the World' jam 'Rooftop' (watch above), but Matthews himself sat down for a two-part interview with Fallon (watch below). He then teamed up with actress Keira Knightley to face off against Fallon and singer Michael Bublé in a round of 'The Musical Instrument Game' (watch at the bottom), which is kind of like 'Name That Tune' meets our Weird Rock Instruments feature.
