With the rise of the Depression, most big bands were being pressured to record more dance band-oriented pop music. Duke Ellington managed to keep his standards high despite occasional vocals from Sid Garry, Dick Robertson, Chick Bullock, and Frank Marvin. Along with some lightweight material, this chronological study of Ellington's work during a six-week period (which has all of the master takes but none of the alternates) is most significant for its early versions of "Rockin' in Rhythm" and "Mood Indigo," a rollicking "Twelfth Street Rag" (with Benny Payne on second piano with Duke), and Ellington's first extended work to be recorded, the moody "Creole Rhapsody." ~ Scott Yanow, All Music Guide
