The quartet settles into a medium-tempo groove for Coltrane's minor blues, the most relaxed swinging number in the second half of the set. At 124 BPM in D-flat, the twelve-bar blues form provides a spacious framework for three featured solos. Lefkowitz-Brown stretches to eleven choruses on tenor saxophone, Feifke follows with seven choruses on piano, and Chmielinski takes a five-chorus acoustic bass solo — the longest bass feature of the session. The twelve-minute performance and generous solo distribution recall the communal spirit of late-night jam sessions, where a simple blues becomes the vehicle for extended exploration. Coltrane first recorded Equinox in 1960 during the sessions for Coltrane's Sound, and its dark, brooding quality has made it one of his most frequently covered minor blues compositions. The tune's relatively straightforward changes, compared to the harmonic complexity of Moment's Notice before it, give the soloists room to focus on melodic development and blues vocabulary. The set concludes with the ultimate Coltrane challenge — Giant Steps.
