The War on Drugs "Red Eyes" (live on 'Letterman')

The War on Drugs 'Red Eyes' (live on 'Letterman')
Philadelphia rock act the War on Drugs recently let loose their Lost in the Dream LP, and even treated it to not one but two North American tours. Refusing to stop the fight, however, they continued their run with a stop on the Late Show with David Letterman.

The already large band was expanded further with some keyboard assistance from one Paul Shaffer. Together, the expanded War on Drugs powered through the breezy anthem "Red Eyes."
