A$AP Rocky appeared on the Late Show With David Letterman last night to promote his major label debut, Long.Live.A$AP. Performing the title track while sitting alone on a throne, things get lively around the 2:35 mark when the seat pulls away to reveal DJs A-Trak and Clark Kent, along with MPC master Araabmuzik who go absolutely buck wild on the beat. How wild did they get? When the song ends, even the usually subdued Letterman can’t hide his excitement. Check it.
