John Coltrane December 2, 1961
The book source notes that this performance was a private recording. The private recording was provided by Mitsuo Johfu. Two concerts were performed, at 6:00pm and 9:00pm but only this one track ("Impressions") exists on private tape recording. The book source notes that researcher Mario Grenz has inferred that the whole performance was probably recorded but because only this one title was broadcast, it is the only one available from this session. The concert was most likely recorded by a Berlin-broadcasting station because Radio Bremen broadcast the jazz program "John Coltrane, Eric Dolphy in Berlin" on April 2, 1962. This broadcast was confirmed but additional details could not be uncovered because of missing documents.
