he most renowned Canadian classical performer of the 20th century, pianist Glenn Gould remains one of the most fascinating and celebrated figures in all of music, the archetypal riddle wrapped inside an enigma wrapped inside a conundrum. A former child prodigy, his piano artistry was unparalleled, yet he often received less recognition as a virtuoso than as a troubled eccentric; a disconnected recluse notorious for such odd habits as wearing a wool topcoat in the dog days of summer, Gould was a sight to behold even in live performances — seated on a low chair and slumped over the keyboard, humming (sometimes singing) audibly to himself as he played, all the while conducting with his free hand. Gould's impossible technique and singular behavior were so hotly debated by scholars that often it seemed that his actual skills were negligible; perhaps it's not surprising that at the age of just 31, he left public performance behind forever, turning instead to broadcasting and writing, as well as an almost obsessive exploration of modern recording technology.
