Sleigh Bells "Young Legends" (live on 'Letterman')
Brooklyn party-starters Sleigh Bells continue to promote their divisive Bitter Rivals, most recently stopping by the Late Show with David Letterman.

Once again introduced as a duo, the group were joined by a seven-piece backing band (eight if you include Paul Shaffer, who joined them on piano) to perform the poppy, acoustic guitar-driven "Young Legends."

Watch the band perform "Young Legends" on Letterman below.
