'Don't Swallow the Cap' isn't just good advice for children from the National -- it's also the title of a tune off their forthcoming album, 'Trouble Will Find Me,' which drops May 21.

Earlier this week, the band issued the disc's first single, a catchy little number called 'Demons,' and 'Don't Swallow the Cap' follows with a more upbeat vibe, complete with swelling, symphonic strings. Check it out below.

Meanwhile, the National are gearing up for next week's premiere of their new documentary, ‘Mistaken for Strangers,’ at the Tribeca Film Festival in New York City. The 12th annual TFF runs April 17-28, and the flick will play on opening night, followed by a performance from the band.
