This Pablo set has odds and ends taken from nine different recording/rehearsal sessions that find Ellington experimenting a bit with instrumentation and personnel, even taking a vocal on the tongue-in-cheek "Moon Maiden." Performances range from a couple of vigorous trio workouts and spots for Wild Bill Davis's organ to a few big-band performances. Even this late in his life, Duke Ellington had a great deal to say musically and his band continued to rank near the top.
