Glenn Gould's piano recording for Bach's Goldberg Variations in 1955 and 1981 are his so-called Alpha and Omega albums, his first and his last. I bought the album State of Wonder (which includes both renditions) yesterday and brought it along for an audio equipment audition with b12. There we were, a handful of strangers sitting in a dark room listening to the album, and the other audiophiles spotted Glenn Gould humming to his piano before I did. It was oddly endearing.
