I have no idea who this guy is, but it was a catchy thread title.  I was all excited to hear this grunting and moaning, and the Amazon.com previews do give a taste of what you guys are talking about.  That is pretty weird I'll admit, but off-mic background noises are something you don't usually get otherwise.  I can see how a whole LP of that could be annoying, though.

I do not know who I hate more, Keith Jarret or John Pizzarelli!!  Mr.Pizzarelli even made humming duets with his own guitar!!
This outcome in nasty music proper to be played in Guantanamo...

If this tape do not stop this annoying guys, maybe the sound engineer should slap the mouth of these guys with his used socks.

I was always used to listening to Glen Gould's grunt-alongs. When I heard the Zenph recording of Goldburg variations, I actually missed the grunts.
