I've got to throw in a plug here for the Swingle Singers, a vocal jazz group in the 60s. They may not be to your taste, but they're very, very good. On the album I had they sing classical pieces in jazz style, with bass and light drums. It's called "Anyone for Mozard, Bach, Handel, Vivaldi?" Good stuff...

Again, I can't say that it's the best mastering job, but it's pretty good considering it was recorded in the 60's.

I am the Doctor, and THIS... is my SPOON!
