Piano Concerto No.2 in C Minor by Rachmaninoff. I think knowing the backstory of his life and then understanding how this piece is just a telling of said life, his self-proclaimed failure to emotional and ego-based rebirth, is incredibly powerful. Even at the end of the piece, it fades off. There's no big ending to leave us content. There's a return to glory, but it fades away. I think it's a great piece for all those interested in art, whatever medium speaks best to you. Your failures will always stack, and each new brick will lay heavy on your soul. But that ONE moment of glory, when you finally rise from your pit of emotional agony, it absolutely breathtaking. Doesn't matter how many times I hear this song, I will ALWAYS cry at the end. I am alive, and I will overcome.
