I took slight offence at the passage "a live performance of a great symphony, in which musical instruments played by humans are never perfectly in tune and occasionally quite far out of tune" after mentioning the Wiener Philharmoniker. I don't think they ever play out of tune. I did hear orchestras play out of tune occasionally, but it has never been an agreeable experience. It never made me think "how human". Instead, hearing a botched entry in the chorale in Mendelssohn 5 helped me understand the brass players' addiction to beta blockers.
