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.

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.

A rare release of vintage Sun Ra remastered from the original tapes, featuring 14 tracks not issued anywhere else on a bonus CD, altogether totaling over 80 minutes of great music.
