Annuals brought “Confessor,” the lead single off their new album, Such Fun, to Late Night with Conan O’Brien on Monday. The band apparently swells to a 10-piece live, and they have three full-time guitarists. Conan seems to dig the performance, and he apparently knows the birthdays of people in Annuals—he wishes the keyboardist happy birthday at the end of the clip.

Such Fun is out now via Canvasback. [via Stereogum]
