Listening to Phil Schaap's podcast on Serge Chaloff (Feb 22, 2016), I came across a remark made by the renowned WKCR DJ who after playing a recording by Chaloff, called it a production of Motif Records, "a Boston obscure 78-era label".
The recording in question from April 16, 1949, entitled
King Edward the Flatted Fifth, featured Boston-born Serge Chaloff (baritone sax), Charlie Mariano (alto sax), Gait Preddy (tp), Mert Goodspeed (tb), Ralph Burns (p), Frank Vaccar (b), Pete Derosa (d).
