The Kills 'The Last Goodbye' on 'Letterman'

Rock duo perform piano ballad from 'Blood Pressures'

Matthew Perpetua

The Kills returned to the Late Show with David Letterman to perform "The Last Goodbye," an aching ballad from their most recent album, Blood Pressures. Though the duo typically relies on drum machine beats and heavily distorted blues guitar riffs, this song strips their sound down to just Alison Mosshart's striking voice and a bed of melancholy keyboard tones.
