There is a time in an artist's career when they go from being super to superstar, and after seeing Janelle Monáe on last night's episode of the Late Show with David Letterman, let's just say that she transformed before our very eyes. For that to have been her network television debut, she worked the stage and the audience like a seasoned veteran. Performing her smash hit "Tightrope," she channeled the spirit of James Brown and got on the good foot, sliding across the stage, doing her funky dance moves and singing her little heart out in her signature lady tux. This was a joy to watch. I'm already looking forward to her next television appearance. After last night, I'm sure the bookings are pouring in.
