Sun Ra "Super Sonic Jazz" LP

Super-Sonic Jazz was the first album to be released on El Saturn Records, the label run by Sun Ra and his business partner Alton Abraham. Set up in 1955, they released their first singles, including a doo-wop group The Cosmic Rays and the Arkestra's Saturn, at the beginning of 1956, and had recorded the whole of their first album by the end of the year, to be released in March 1957. El Saturn is now considered, along with Charles Mingus and Max Roach’s Debut label and Harry Partch’s Gate 5 label, "one of the very first and most active artist-owned record labels." Often pressed in editions of 75 — sometimes as few as 20 were made for specific concerts — the records would be manufactured using local black businesses, and often put together in Abraham's own home.
