Esperanza Spalding 'Radio Song' on 'Letterman'

Jazz fusion singer performs 'Radio Song'

Rolling Stone

Esperanza Spalding turned up on last night's episode of the Late Show with David Letterman to perform "Radio Song," a number from her new album Radio Music Society. The tune is about as pop as the fusion singer gets, but there's just enough jazzy flair to it to keep it from seeming like pandering to a mainstream crowd.
