Erykah Badu is compelling on her own, charismatic and natural, with a voice that soaks into your skin and leaves you wanting more. Put Mark Ronson, The Dap Kings and Zigaboo Modeliste behind her, and you’ll be swooning for days. Performing their collaborative track, “A La Modeliste,” last night on The Late Show With David Letterman, Letterman himself summed it up to perfection at the end of the show, saying, “That’s it, that’s all you want, right there. That’s all we’re looking for!” And it really is. Start your day listening to the soul-filled song, from the joyful brass section, to Badu’s arresting voice and Ronson’s modest guitar and genius production skills. It’s all you need.
