It would be useless to describe the playing of Erich Zann on that dreadful night. It was more horrible than anything I had ever overheard, because I could now see the expression of his face, and could realize that this time the motive was stark fear. He was trying to make a noise; to ward something off or drown something out—what, I could not imagine, awesome though I felt it must be. The playing grew fantastic, delirious, and hysterical, yet kept to the last the qualities of supreme genius which I knew this strange old man possessed.
