[UPDATE: This show has been rescheduled for Nov. 19.] British band Alt-J's debut, An Awesome Wave, was just nominated for UK's prestigious Mercury Prize, but it's making waves all the way across the Atlantic, too. Their hook-filled blocks of pop have resulted in one of the year's most striking debuts. Tonight they open for the relatively meh Grouplove, but Alt-J won't be a supporting act for much longer.
