WATCH: The Black Keys Perform From A New York City Fire Escape

A Live On Letterman webcast like no other.

Last night, from a fire escape outside the Ed Sullivan Theater in New York City, The Black Keys played a special outdoor Live On Letterman webcast concert. The set clocked in at just over a half-hour and boasted a stellar setlist of the band's hits, including "Gold on the Ceiling," "Howlin' For You," and "Tighten' Up." Dan and Patrick also performed the singles "It's Up To You Now" and "Fever," from new album Turn Blue, for one of the first times to a live audience. The entire performance is available for viewing online now and you can watch it in the player above.

The Black Keys latest LP Turn Blue is out today on Nonesuch Records.
