Good Recommendations For Scat Singing Please

Sarah Vaughn and Mel Torme.
Mel was an outstanding musician and the most underrated jazz singer in history.His perfect time showed how he listened to and respected the "guys in the band" .
He had a truly amazing ability to instantaneously mimic the overtones of any instrument that came in.
Never heard anything like it or ever expect to this side of heaven.

To my jaded ears, great as Ella was. I could never shake the feeling she'd rather be somewhere else doing something else.

With Sarah it seemed she wished for nothing but to sing and that the song would never end.

Mitch, start with " Mel Torme Swings Schubert Alley" on Verve 5166798 . A 1960 recording before he became the " Velvet Fog".
Not a lot of scating on it but what there is constitutes a Master Class.
Simply the best male vocal album I ever heard.
The rest of my Torme is loaned out to a friend.

Best scatting I ever heard was "Autumn Leaves" on Sarah's album "Crazy and Mixed UP" " a 1982 Pablo Release. A real jazz album.
Another great album is "Sarah Vaughn with Clifford Brown" which is in lovely 1954 mono. Not too much scatting but what there is is sublime. " Lullaby of Birdland " in particular.
Sarah was a good pianist and musician, from what I've heard a singer is who IS a musician gets to the heart of the matter better than someone who just has a good or even great voice .
IMO she was the greatest of all female jazz vocalists.
