The Heliocentric Worlds of Sun Ra, Volume 1
The Heliocentric Worlds of Sun Ra, Volume 1 is a 1965 album of compositions and arrangements by Sun Ra played by Sun Ra and his Solar Arkestra. It was recorded at Studio RLA in New York on April 20, 1965, engineered by Richard L Alderson. The music is heavily percussive but dispenses with a continuous beat, reconstructing itself around interweaving compositional and improvisatory creative principles with programmatic affects. It exemplifies a radical break from previous notions of melody or harmony. The interwoven lines of Ronnie Boykins' bass and Sun Ra's electronic keyboards provide cohesion. Sun Ra directed the session in real time—stopping takes, assigning rhythms, revising horn parts, and reassigning solos based on his understanding of each player's strengths. The album was originally released with a black-and-white sleeve designed by Sun Ra. It belongs to Sun Ra's New York phase, marked by experimentalism, tape delay, spatial sound, free improvisation, expanded instrumentation, and pioneering use of synthesizers and electronic keyboards.
