A lost slice of work from Sun Ra's early 70s years on Impulse Records – one of the few new recordings created for his association with that label (most of the titles were reissues of earlier Saturn albums) – but one that was never issued at the time. This 2018 issue adds a disc of session recordings from the same period and with pretty much the same musicians, including Ronny Boykins on both discs.

Digipak has some edge wear and minor scuffing.
