Around 1968 or so, I was asking a fellow Temple student what he would be doing over the weekend. A math major, his answer surprised me. He said he was going to a concert in Fairmount Park to see Sun Ra. Never heard of the guy until then. Turns out he was a jazz innovator and possibly alien visitor. The Youtube below is an appreciation by some remaining members of the Arkestra and members of the Berklee music faculty honoring the 100 years since his birth.
