Following the National's ‘Letterman’ performance of ‘Don’t Swallow the Cap’ on Monday night (May 20), the show’s host complimented the Brooklyn-based band on a job well done, appropriately remarking, “A lot going on there.” Yes, there was, as Thomas Bartlett — who goes by the stage name Doveman — sat in with the group on keyboard, joining the string and horn sections also guesting on the tune.

The performance was just in time for today’s release of the National's sixth full-length album, ‘Trouble Will Find Me,’ on which ‘Don’t Swallow the Cap’ is the third track. If you missed last night's performance, get a recap above.
