I hate Gould, particularly for his tuneless singing with the piano, which destroys any sense of the piece I am listening to. If you don't hear it, replace your cell phone with a real highfidelity appliance. I watched a whole "American Masters" program on Gould on PBS in 2012, and came away with the sense that Gould is a fine looking tall person of northern European origin, which seems entrance the eyes and block the ears of certain reviewers. As I don't live in NYC or Toronto, I had never seen Gould. See the other threads here about how contests are judged with the eyes. I've detested Gould on Colombia LP's since at least 1971, There were really no other JS Bach LP's available in my oil town except E. Power Biggs, who I admired greatly but played the pipe organ or harpsichord. For clavier JSB pieces I followed my teacher's interpretations, but have branched off some as I learned the inventions she never heard me play.
I heard a Schiff performed JS Bach piece today on WUOL-FM, and it was competent. More than I can say about Gould. Schiff didn't follow Busoni editions, which is what I start with, As m1469 says, there are a lot of ways to play JS Bach, since he didn't write a lot of performance instructions. The variations of different performances make life interesting. The singing, Gould's parents should have disciplined him more often. My Father stopped me from tunelessly singing in the car when I was seven, and I've never forgotten. Sing on pitch, in rhythm, or don't sing at all.
