Of all the jazz musicians, Sun Ra was probably the most controversial. He did not make it easy for people to take him seriously, for he surrounded his adventurous music with costumes and mythology that both looked backward toward ancient Egypt and forward into science fiction. In addition, Ra documented his music in very erratic fashion on his Saturn label, generally not listing recording dates and giving inaccurate personnel information, so one could not really tell how advanced some of his innovations were. It has taken a lot of time to sort it all out (although Robert L. Campbell's Sun Ra discography has done a miraculous job). In addition, while there were times when Sun Ra's aggregation performed brilliantly, on other occasions they were badly out of tune and showcasing absurd vocals. Near the end of his life, Ra was featuring plate twirlers and fire eaters in his colorful show as a sort of Ed Sullivan for the 1980s.
