I don't know if he's aspie, but he's definately a fellow Space Cadet. Predated Pink Floyd and Star Wars. After reading his biography, I was shocked by how similar his ideas were to mine about space and music, considering our age and cultural differences...I had a character called the Space Cadet and his enemy was the Overlord. Sun Ra had, well, Sun Ra, and his villian's name was...the Overseer (in SPACE IS THE PLACE.) And set to music, nonetheless...
Some of his music is beyond me, other albums I like. Worth a listen, if you're adventurous.
