Lord lists one unissued alternate take from a Buck Clayton session. Studying the release history in different formats, often adding new tracks from the same session, suggests there might be more. But getting those tracks in session order and from good sources justifies such a set, given the excellent recorded sound of this music.
HEP in England also issued several discs of AFRS Jubilee material, West Coast big bands, Raeburn, Benny Carter etc. Always good music.
There was a discography by Rainer E. Lotz and Ulrich Neuert, published in 1985 by Norbert Ruecker.
The b flat major concerto from these, which I will be going to hear live this evening in the exams performance of Korean harpsichordist Hwan-Jeong Lee in Frankfurt:
All the "unreleased" tracks were on the CDs Michael Cuscuna produced for Roulette twenty years ago. I have them all and compared track listings. But back then only few people took notice.
Now Scarlatti from this box:
Marcelle Meyer was the fastest hand ever among classical pianists, knew no technical imits but never sounds like showing off. She simply played the music. Even the pieces Stravinskij dedicated to Rubinstein and Horowitz that they avoided but did not admit that they found them too hard to play. Highly recommended!
