I love psychedelic, bizarre, spacy type music. I'll give my five biggest recommendations on albums in that general area...

Hawkwind-- In Search of Space

Steve Roach-- The Magnificent Void

Kevin Braheny-- Galaxies

Dominic Woosey-- Mysteries of Science: The Erotic Nature of Automated Universes

Jon Iverson-- Alternesia

All of those are very incredible. Hawkwind was a rock group, but they were also space musicians who played with strong jazz and folk elements. The last four are just straight up space music, and it's the best I know of in existence.
