Alabama Shakes "Hold On" (live on 'Letterman')
Traditional rock'n'roll and Southern soul revivalists Alabama Shakes were on the Late Show with David Letterman last night (April 12), delivering their track "Hold On."

The song is the first single off the Athens, AL group's recently released and highly touted debut full-length, Boys & Girls.

Letterman seemed genuinely impressed with the Shakes' blistering performance. See for yourself below courtesy of Audio Perv.
