The CD version I have is called Spike Hughes & Benny Carter. Great disc with very good sound. And besides Carter, there's also Coleman Hawkins, Chu Berry, Dickie Wells, and Sid Catlett...
I have two other retrievals: Spirits of Rhythm (Leo Watson!), and The Boswell Sisters Airshots and Rarities 1930 - 1935. Wouldn't want to be without either one.
The other two you mentioned sound well worth pursuing, Late.
