Yesterday i saw a 2 hour documentary a bout Glenn Gould on national tv. There were random visual clips from various live performances pluss many other clips as well as live recs I have never heard before.
This was of course great but the strangest part was when they played a private recording from 1948 of Glenn Gould playing Chopin`s 10.2 at an insane sdc speed!
Other stuff was goulds own transcription of Schubert 5th symphony and more.
