[2] Tracks 1 (as "Barracuda", or "General Assembly"*), 8, and 9 (in a 9:37 edited version) first appeared on LP in 1974 as part of Verve's "Previously Unreleased Recordings" series.

That album also contained two quartet pieces, "Blues In Orbit" (or "Cheryl"*) and "Isabel" (or "The Underdog"*), which are not available on CD.

In the UK, the original album was issued by Verve for the first time in 1974 but as a double LP, with different cover art.

It included the tracks from "Previously Unreleased Recordings", giving some alternative titles (*) to those on the US release.

The Allmusic review by Scott Yanow awarded the album 4 stars stating "Highly recommended to Gil Evans fans; it is a pity he did not record more during this era".
