One of the most idiosyncratic and charismatic musicians of the twentieth century, pianist Glenn Gould (1932–82) slouched at the piano from a sawed-down wooden stool, interpreting Bach, Beethoven, and Mozart at hastened tempos with pristine clarity. A strange genius and true eccentric, Gould was renowned not only for his musical gifts but also for his erratic behavior: he often hummed aloud during concerts and appeared in unpressed tails, fingerless gloves, and fur coats. In 1964, at the height of his controversial career, he abandoned the stage completely to focus instead on recording and writing.
