'The test pressing was made at Sheldon Recording Studios (aka the Chess studios in Chicago) and titled simply, ''Music of the Future'' by Sun Ra Arkestra. Side A contained “Space Mates,” “But Not for Me,” and “The Others in There () World.” Side B had “Lights on the () Satellite,” “Day by Day,” “Ankhnaton,” and “Holiday for Strings.” The pressing contains Alton Abraham's home address at 4115 South Drexel and gives a Montréal address and phone number for Sun Ra. It was therefore cut in August or September 1961. However, the Arkestra's relocation to New York disrupted the plan. Saturn did not actually issue any LPs from this session till 1965, and when they began to appear, the tracks had been redistributed.〔
