Larry:
Our colleague C.J. Hazevoet compiled a very detailed and thoroughly researched two-part discography/sessionography of Don Byas, as the starting point for an ongoing and wider Byas project, which in his own words, "in due course will hopefully result in a comprehensive work on the tenorist’s ‘Life and Work’".
I'm proud of having modestly contributed with some research on the months Don Byas stayed in Spain.
Best regards,
Agustín
