When Ari Lennox entered NPR Headquarters to perform at the Tiny Desk, we soon learned she was a little under the weather. Draped in a long, leopard-print coat, she greeted the band and approached the desk. I asked her if she was in any shape to sing, and she assured me she was. "Oh, I'm fine and I'm ready!" With that, she slipped off her coat, took her place behind the desk and began her warm up.
