During the mid 1960s, Duke Ellington was constantly recording his own musical ideas and projects with the hope and intent that a label would pick them up, as albums, and then commercially release them. However in some cases the projects were never fully completed in terms of an album's length of work, or were just never accepted by the labels and were otherwise left in Ellington's vault of recorded masters, as well as unmixed sessions. In this release, we explore some such works; parts of an Ellington album that was planned as a feature for trumpeter Ray Nance, a few miscellaneous studio versions of important songs he was playing out on the road, as well as a very obscure small group led by his son Mercer Ellington, featuring a very young Chick Corea on piano. The sessions range from 1962 to 1966, and they contain a whole lot of important music that Ellington fans need to hear.
