Sun Ra - The Heliocentric Worlds of Sun Ra Vol 3 (1966 rel. 2005)

This previously unreleased recording is taken from the record session for Heliocentric Worlds Volume II, on November 16, 1965, at the RLA Studios in New York City.  Lost for over 35 ears, it has now been found by the Good Doctor, who brought it to ESP.  Deterioration of a portion of the tape required the deletion of about one minute of music, but you won't notice it. 
During this period, Sun Ra joined other ESP artists on a six concert tour of New york State colleges.  Sun Ra kept all of the tapes, except for NOTHING IS, ESP 1045, which he delivered to ESP.
From the CD Liner Notes

Volume 3, subtitled “The Lost Tapes” offers material not previously available in any of ESP-Disk’s earlier incarnations. The centerpiece is a seventeen-minute episodic adventure that cycles through solo segments for Gilmore, Patrick and Allen, each in intense and exemplary form backed only by Ra, Boykins and Blank in various combinations. Eruptions of layered horn polyphony bracket the fulminating improvisations. Mid-piece the energy folds into a splenetic two-fisted improvisation from Ra as the horns circle in for a final rocket-fueled blowout and reverie-structured coda. The remaining four tracks form a microcosm of interests. The moody percussion thicket of “Mythology Metamorphosis,” serves as a return vehicle for Ra’s tuned bongos and marimba. Allen’s nasalized oboe and a strong pizzicato undercarriage by Boykins flesh the piece further. “Heliocentric Worlds” and “World Worlds” arrive like outtakes from an earlier 60s Arkestra album (say Fate in a Pleasant Mood or The Nubians of Plutonia) with structured themes and solos threaded by the horns and the Ra’s bright acoustic and electric chords between washes of cymbal-heavy percussion. “Interplanetary Travelers” employs Ra’s various keyboards as the cynosure of a grand, if brief, saturnalia of dissonant horn voicings and thickly boiling interplay.

The recording opens with a sparse "Intercosmosis, where John Gilmore shapes his boat-horn of a tenor around around some abstraction. Sun Ra and bassist Ronnie Boykins enter with a repeated line that further highlights the energy. Pat Patrick's baritone enters, and he and Gilmore twist solos around each other.

The percussion-laden "Mythology Metamorphosis features a brief bit of Marshall Allen's snake-charming alto before Boykins' solo takes it home. The three remaining pieces, each clocking in around five minutes, hint at Ra's elusive live performances. "Heliocentric Worlds has him switching from piano to one of his early electric keyboards, as does "World Worlds, where he does an alternating hands electric/acoustic combination. The final "Interplanetary Travelers" has an all-too-brief Sun Ra energy jam.
