Future Islands, who just finished wrapping up their biggest Northeast tour yet, will be debuting on 'Austin City Limits' on Jan. 17 -- but that's not all. They'll be sharing the episode with one of pop music's biggest artists, Sam Smith.

The kooky indie rock act will perform their song 'Balance' and four tracks from their newest LP, 'Singles,' including 'Back In the Tall Grass,' 'A Dream of You and Me,' 'A Song for Our Grandfathers,' 'Seasons (Waiting on You)' and 'Spirit.' And if this will be your first time seeing Future Islands live, get ready for some very interesting dancing from frontman Samuel T. Herring. You can find out more details about the episode here.

Future Islands will also be heading out on a brief southeast tour in April; check out the dates below.
