I don't have those recordings, but it is not unusual for an instrumentalist to vocalize while playing. They hum or sing along as they play. It gets picked up a lot on close miked piano recordings where the microphone is hung above the strings. Keith Jarrett is a prime example. He gets so loud and annoying that despite some wonderful playing I can't listen for long. He sounds like a wounded cow to me.
strange sounds on rvg recordings/ or i'm crazy
I just recently have discovered jazz. having a great time.something i just noticed on two newly purchased cd's, both bluenote, i hear someone vocalizing during the songs. the first one is art blakey "free for all" and the other is Bud Powell "the scene changes". Am i crazy does any else hear this. I was attracted to jazz, blue note and Rudy van gelder after a discussion between engineers about gelder's secrecy surrounding his recording techniques(mic choice and placement) and that he went so far as to put up different mics for photographs. As i recording hobbyist and i thought that was a cool story even if not true.
