You needed love to win at the game of music...I played of sadness. I played of loneliness. Despair. Love found and lost. I played of tragic misunderstanding and weary cynicism and defeat. I played of perseverance, endurance beyond all suffering. Endurance in the face of hopelessness, hope when even hope was a betrayal...And yet, though I played so much sadness, the music at the same time denied despair. How could anyone despair while music was being played?
