What's your latest album purchase?

What freaks me is to hear Mel instantly fill in an error from a player with his voice with the same harmonics and pitch of the player.
I have no doubt, leaving vocals aside,that Mel was the
finest pure musician of all jazz vocalists.

I can only echo Mapman and Schubert. Mel has a very special vocal presentation. Eerie comes to mind in his ability to hold a note and be more accurate than the brass instrument. The horn section could tune there instruments to Mels voice. :)

I know tuna fish but not tune a horn :)

When he does it, his voice does not sound real, more unreal or synthesized, but I am pretty sure that it is just him. I also have his Classic Concert live recording from Carnegie Hall on Concord jazz label and it is on display there live.

Try his Christmas Album, some unreal feats on it.
