The phrase "Once in a lifetime" is sometimes used carelessly to accentuate the importance of an event. But it was truly a unique occasion when the orchestras of Duke Ellington and Count Basie got together in the studio to record together for the first (and last) time. The Duke Ellington and Count Basie (both playing the piano) orchestras had already been competitors for 25 years but the leaders' mutual admiration (Ellington was one of Basie's main idols) and some brilliant planning made this a very successful and surprisingly uncrowded encounter. The result is almost an embarrassment of riches.
