"Did you know that the human voice is the only pure instrument? That it has notes no other instrument has? It's like being between the keys of a piano. The notes are there, you can sing them, but they can't be found on any instrument. That's like me. I live in between this. I live in both worlds, the black and white world."

(Nina Simone, nome d'arte di Eunice Kathleen Waymon, cantante; Tryon, 21 febbraio 1933 – Carry-le-Rouet, 21 aprile 2003)
