Sun Ra was one of the greatest and least known jazz artists of the last four decades, whose influence on diverse musicians is little known to the general public. A pianist and band leader, his style ranged from retro swing to avant free, and often in the same piece. His band could play a swinging Gershwin tune and almost imperceptibly soar into their free cosmic equational tones as if they possessed a single mind.

Ra, or "Sonny" as some called him, was a keyboard improviser of great originality, but I think his foremost talent was for inspiring and teaching creative musicians to improvise freely but together. This tension between freedom and coherence was something he explored with abundant energy and skill.

Sun Ra took his leave of us in 1993. Before that, I was fortunate enough to see him with the Arkestra live twice in the mid-80s: once outdoors at Princeton University, and once at the Palomino in Los Angeles. None of their many recordings quite captures the live fury of this amazing ensemble.

The Arkestra still performs today, under the able direction of alto saxophonist Marshall Allen. Sun Ra said and wrote many strange things while he was upon this planet. The easy, mindless reaction is to just label him "weird" and hide behind that facile label. Another possibility is that he was passionately engaged in and by his creative mythology, and that what he really meant could only be articulated in his music.
