At the time of this session Gillespie was under contract to Musicraft Records, so he is listed as "Hen Gates."

John Mehegan's "Special Notes and Commentary" to the original LP release (Savoy MG-12079) are the source of much confusion about this date. He claims, for example that Bud Powell is the pianist, when in fact Powell was states away recovering from a breakdown.

There has been a lot of debate about who plays the eight-measure trumpet solos at the beginning and end of "Ko Ko." Most of the critical weight seems to be in favor of its being Gillespie, who (unlike Davis) was familiar with the theme and the arrangement, and who repeats the solo almost verbatim when playing "Ko Ko" at Carnegie Hall in September 1947. The case for Gillespie is laid out in detail by Brian Harker in a 2021 essay, "Miles Davis, 'Ko Ko,' and the Making of a Fallacy" published in Jazz Perspectives (https://doi.org/10.1080/17494060.2021.1970611).

Tommaso Urbano has argued on the basis of the aural evidence that it is Davis, not Gillespie, playing trumpet on "Ko Ko." He also argues that, although Gillespie plays the piano introduction on take 1 of "Thriving on a Riff," it is Argonne Thornton on the second and third takes. See his excellent website, The Music of Miles.

Although Davis seems unsure of himself in places, his style and harmonic sense is already present -- listen especially to his playing on "Now's the Time" and "Thriving on a Riff."

Thanks to Tommaso Urbano for discussion of this session, and to Carl Woideck, who discussed the session and shared Brian Harker's essay with me.
