Sergei Prokofiev's opera
The Fiery Angel—a medieval tale of demonic possession and its erotic overtones—was never produced during his lifetime. But he felt it contained some of the best music he had written, so he brought it to life in the concert hall as his dark, dynamic, and dangerous Symphony No. 3. How he got it past the Soviet censors is a mystery; you may find yourself looking over your shoulder after hearing it!
