This is the only commercial recording of the Billy Berg band with Parker, who failed to show up for the follow-up Dial session on February 7. At this second session Gillespie re-made "Diggin' Diz" (which was given the title "Diggin' for Diz") and added two takes of "Dizzy Atmosphere" (released as "Dynamo A" and "Dynamo B" and beginning discographical confusion that continues to this day); "Confirmation"; and two takes each of "When I Grow Too Old to Dream" and "'Round Midnight." The February 7 session was originally supposed to include Lester Young, who never showed up; Lucky Thompson was at recruited at the last minute to take his place.

Later in February Parker signed a one-year exclusive contract with Dial.

I am grateful to Leif Bo Petersen and Chieo Yamada for help with this session.
