The terrific Robert Glasper stopped off at Letterman last night for a leap day performance of “Always Shine”, a track off the recently released Black Radio. Glasper’s magic fingers and production genius provided a perfect playground for Lupe’s lyrical talents and Bilal’s crooning hook. So sit down, relax, turn the lights down and get real soulful with Rober Glasper, Lupe Fiasco, and Bilal.
