Yeah, Sun Ra has quite a plethora of recordings out there. I still haven't gotten around to collecting much of his stuff (though I do have a couple private piano recordings). The dude played so many styles of music that it's impossible to fully appreciate his supreme oddness.
Some GREAT players passed through his band over the years, one of my favorites is tenor man John Gilmore.
One of my buddies has a large number of his recordings, I"ll try to get some suggestions from him.
