Pianist Oscar Peterson and flugelhornist Clark Terry always made for a perfect matchup. Their duet set (one of five Peterson made during this period) is quite friendly, witty and hard-swinging. C.T. generally sets the joyous mood and on numbers such as "On a Slow Boat to China," "Shaw 'Nuff," "No Flugel Blues" and "Mack the Knife," the warm-toned flugelhornist shows that he was one of the few who could truly keep up with the remarkable pianist.
