The third tune introduces a waltz feel at 186 BPM, with Fats Waller's elegant composition providing a rhythmic departure from the straight-ahead swing that bookends it. The expansive 64-bar ABAB' form gives each soloist room to develop ideas over the longer cycle — Cohen takes two choruses on piano, Jones follows with three on trumpet, and drummer Kyle Poole takes a rare featured spot with two choruses of drum solo in waltz time. The eleven-minute performance showcases the quartet's comfort in three-four time, a meter that demands different phrasing instincts from the standard four-four swing feel. Waller composed Jitterbug Waltz in 1942, and despite its playful name the piece has a sophisticated harmonic structure that has attracted jazz musicians for decades. The waltz format sits between the relaxed blues of No Blues and the dense bebop harmony of the next tune, Hot House.
