Before last night, the Portland/New Zealand indie-pop trio Unknown Mortal Orchestra had never shown their faces on American television. But they still looked pretty casual on last night’s episode of Late Night With Jimmy Fallon, chewing gum and keeping their eyes downcast as they ran though “So Good At Being In Trouble,” the oddly funky jam from their recent album II, building to a beautifully shred-happy climax. Watch the performance below.

II is out now on Jagjaguwar.
