Two nights ago, Chad Hugo and Shay Haley closed the Late Show with David Letterman like this. Accompanied by two sinuous black women (intent on shaking their bodies) and by a train of lean, white female models sitting still at the feet of Pharrell, N*E*R*D* took advantage of their visit to present live “Hypnotize You”, one of the songs featured on their upcoming album, “Nothing”. Look at Chad Hugo behind the synth, his face half covered by a sort of balaclava. A wink to Daft Punk? Possibly so. The authors of “Human After All” are the producers of the song.
