A collection of torrid live club performances at the legendary NYC venue Slugs. Originally released in 1972, these recordings provide an intriguing glimpse of the Arkestra's repertoire and virtuosity towards the end of their first decade in New York. Universe In Blue has never been available on CD, and only a previous unofficial vinyl version was available prior to 2022.

Includes liner notes by Irwin Chusid, and an expanded essay by Jazz historian Ben Young.
