Congratulations to Alt-J, the UK-based experimental pop four-piece, for winning Britain’s prestigious Mercury Prize yesterday. Earlier this year, the band appeared on World Cafe and performed three songs – “Fitzpleasure,” “Tessellate” and “Breezeblocks.” Listen to the entire session, plus the band’s interview with David Dye, here; for more, see photos and a review of their recent Johnny Brenda’s appearance here.
