Quotes from Paul S in blue :
"...This LP features the usual stretched (stereo) keyboard..."
Man, I don't understand why they do this! There used to be a piano in my house, making it easy to compare real piano to recorded piano... The real piano NEVER sounded as if the sounding board spanned the entire width of the room!
Sometimes I play a full length (88-keys) synthesizer through the audio amps and the horns; connecting the synth via its left and right outputs does not result in the above-mentioned spacial garbage... Which I find even more insulting when applied to a drum kit! Its as if the drummer were running back and forth across the stage!
"...Then there is Gould's humming, nicely pitched and complete with vibrato..."
And then there is Mr. Kieth Jarret's humming!
Rather his un-containable "cries of joy" (not nicely pitched, often off-key, and at times sounding like bits of a porn clip). This just ruins it for me, as I start to take on responsibility for the acts of the performer, which makes me start to sweat! Ok, its his choice, but it might enlighten Mr. Jarret if someone were to separate out that part of the recording and play it back for him as one long a capella track !
That said, as one can see in the photo, his piano is thankfully not miked for the stretched effect.
