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.

Merging and remastering two essential albums from free jazz saxophonist Marion Brown: his 1966 ESP album "Marion Brown Quartet" with trumpeter Alan Shorter, bassist Reggie Johnson and percussionist Rahied Ali; and his 1967 Fontana album "Juba-Lee" in a septet with Reggie Johnson, drummer Beaver Harris, pianist Dave Burrell, trombonist Grachan Moncur III & saxophonist Bennie Maupin.

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.
