Duke Ellington may have turned 70 in 1969, but he was never short of energy, creativity and innovations. At the time of this Nov. 2, 1969 concert in Copenhagen, Ellington had been leading his orchestra for 44 years, but he still never really looked back in time or sought to recreate the past. Even when he performed older favorites, they were rearranged and full of surprises, and Duke's own piano playing was modern, percussive and unpredictable.
