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.

Most of the RVG remasters are great. If you want to hear some first rate mumbling on a jazz recording try most anything from Charles Mingus. Oscar Peterson sings along almost like a scat-man sometimes. I think it is really cool and find it much more involving to hear these guys bop-be-dee-ba-bop.
although not on the rvg's i find the most amount of mumbling i have come across is from erroll garner. since i upgraded my equipment i find it difficult to listen to. they should put on the credits that he plays piano and mumbles.
You're not crazy. Art Blakey seemed to grunt/moan/scat as he hit every lick sometimes.

But man, listen to Caravan. What a phenomenal record. I can overlook the noises!
One the most famous for this, although not jazz, was Glenn Gould humming along with Bach. I like the live jazz Cds with the humming and grunting, bystanders gabbing, glasses and icecubes clinking along. Makes you feel like you're there. Wasn't one of Blakey's albums called Moan'n?
I have several instrumental Cds where performers breathing is distinctly audible. Definitely miked too closely and is very annoying.
