Jazz By Sun Ra (later titled Sun Song) is the debut album to be released by Sun Ra. The record label for the first pressing says "07-12-56", presumably when it was recorded. The LP originally appeared on Tom Wilson's short-lived Transition Records. In the mid-1960s it was purchased (along with much of the Transition catalog) by Delmark Records owner Bob Koester, finally being reissued in 1967. Earlier home recordings by Ra, including one dating from 1948 or 1949, were released with tracks from 1973 on the album Deep Purple.
