All of the Byas small group sides made stateside as leader in the 1944-1945 timeframe are available on a 4-CD set on Definitive. It has material that he recorded as a leader for Savoy, Jamboree, Hub, Super Disc, American, National, Arista, International, and Gotham, as well as sideman sessions with Little Sam & Orchestra, Albinia Jones, Eddie Heywood, Emmett Berry, Hank D'Amico, Cyril Haynes, Nat Jaffe, and Johnny Guarnieri. I don't routinely buy material on Definitive, but it filled some gaps.
