This 1950 album was a risky and ambitious undertaking by Columbia. It contains four "concert" selections by Ellington, that is, ten to fifteen minute performances. Before the age of long playing albums, artists were limited to three minutes per side. Nobody knew how audiences would react to such lengthy cuts. To enhance the project's riskiness, Ellington's modernistic suite, "The Tattooed Bride" is included. In truth, this record didn't sell very well. Only hard core Ellington enthusiasts were interested in it. But I've gotten a lot of enjoyment out of it.
