Originally released in 3 LPs as Live in Egypt on Thoth Intergalactic and then as the Saturn albums Dark Myth Equation Visitation, Nidhamu & Horizon, this set reissues and expands the 1971 Sun Ra tour recordings: The Mena House Hotel in Giza; a concert at Hartmut Geerken's in Heliopolis; a live Cairo TV channel broadcast; and a concert at Cairo's the Ballon Theatre.

This 1983 Saturn Research LP presents two sides of the Sun Ra Arkestra, the first side with the 80's classics "Nuclear War" along with "Retrospect" and "Makeup"; the second side presenting the extended and more experimental "A Fireside Chat with Lucifer", a 20 minute well balanced, open framework that allows for both melodic soloing and extended free exchanges.

The first new Sun Ra Arkestra album in twenty years, recorded in Philadelphia under the direction of saxophonist Marshall Allan, with long-standing Arkestra members including Danny Ray Thompson, Michael Ray, Vincent Chancey, Knoel Scott, Cecil Brooks, Atakatune, Elson Nascimento and Tyler Mitchel, with new material and new renderings of classic Ra compositions.

The two volumes of "Heliocentric Worlds", recorded 7 months apart in 1965, represent perhaps one of greatest chapters in Sun Ra's legacy, bringing together his immense orchestration skills with future-leaning free jazz, allowing his players expanse inside disciplined compositions that reflect on both space and the then-new freedom explored by jazz soloists.
