The most unusual selection on this Al Cohn-Zoot Sims set from 1960 is "Improvisation for Unaccompanied Saxophones," a short but effective two-tenor workout that, through a clever arrangement by Cohn, gives one the impression that both saxophonists are using circular breathing. Another departure is "Angel Eyes," which has both Cohn and Sims switching to clarinet and showcases Major Holley's singing and bowed bass. Otherwise, the co-leaders stick to their main instruments and enjoy swinging together with the assistance of Holley, pianist Mose Allison (who would soon be starting his own successful solo career), and drummer Osie Johnson.
