...would not be enough for this extraordinary treasure trove of intelligence and beauty. You get to see Gould in real time, talking at length about the music that meant everything to him -- not just Bach and Schoenberg, but Richard Strauss. Mahler, Shostakovich, Prokofiev, and Beethoven, among others. These are complete programs, so you get to marvel not only at the transcendent performances but at the ease with which Gould enters into, say, a Bach fugue, whether for a few measures or for the entire piece, and then reemerges to deliver some extraordinary insight in a mannered but impeccable spoken prose... This set is the bargain of the century at the present amazon price ($72.99) but even if it goes back up to list price the decision to buy this would be a no-brainer. Wow.
