This was the fifth album by the Arkestra to be released, and was the first to be taken from recordings made at the Choreographer's Workshop, New York. Other albums recorded there include 'Art Forms of Dimensions Tomorrow', 'Bad and Beautiful', 'Cosmic Tones for Mental Therapy' and 'Other Planes of There'. The New York period saw Sun Ra focusing far more on percussion backdrops as opposed to horn arrangements (virtually everyone on the album gets a percussion credit), and everything from the percussion to the horn solos to Ra's piano playing took a more aggressive stance. John Gilmore's tenor solo on 'Calling Planet Earth' throws the bop rule book out the window, and he is heard developing a more extended vocabulary of skronks and squeals. This track exemplifies the change in sound and focus from the Chicago days.... When Sun Comes Out is a first glimpse into an era that would culminate in some of the Arkestra's most renowned recordings.
