Thelonious Monk's angular bebop composition returns the energy to medium-tempo swing at 136 BPM, with all three melodic voices contributing. Dillard leads with three choruses on tenor saxophone over the 32-bar AABA form, Cohen follows with two on piano, and Wolfe adds one on bass, with the tempo gradually easing across the three solos. The ten-minute performance showcases Monk's distinctive compositional voice — the melody's unexpected intervals and rhythmic displacements demand careful navigation from the soloists. Monk first recorded Four in One in 1948, and its tricky melody has made it a challenging but rewarding vehicle for improvisers who can absorb its angular logic. Coming after two consecutive performances without the horn, Dillard's return to the solo section re-establishes the full quartet sound. The set then shifts to another ballad with What's New before closing.
