Premise: Blues in Orbit is an album by jazz composer, arranger, conductor and pianist Gil Evans, recorded in 1969 and 1971 by Evans with an orchestra featuring Jimmy Cleveland, Howard Johnson, Billy Harper, and Joe Beck. The album was originally released on the short-lived Ampex label as Gil Evans but received wider release on the Enja label under this title.
Hypothesis: Gil Evans renamed his album when it was re-released by a second record label.
