The Black Keys Live on 'Letterman'

The Black Keys Live on 'Letterman'
It's release week for the Black Keys, and the garage-rocking outfit swung by the Late Show with David Letterman to perform some material from the new album Turn Blue.

They appeared on an outdoor street-side stage in New York. For the televised part of the performance, the duo ran through the single "Fever" plus the bluesy "It's Up to You Now" while accompanied by a couple of backing players. They also played a longer set for the Live on Letterman webcast, with the whole thing clocking in at more than half an hour.
