I just listened to this piece for the first time in a few years, sitting down in front of my stereo after dinner. It was very civilized, especially with a Guinness Stout in hand. I have the recording with Richter and the Borodin Quartet (I should put it in Recommended Recordings). But here’s Glenn Gould and an uncredited string quartet (probably the Symphonia Quartet) playing the finale. Note that Gould is playing from memory, an unusual and unorthodox thing to do in chamber music.
