Sun Ra's live "Concert for the comet Kohoutek" from the 1970s will shake your socks off if you can ignore the mediocre sound quality. The "Journey through the outer darkness" is the most spaced-out, totally free yet precisely executed synthesizer solo I ever heard; and the way he sets his electronic organ on fire in "Unknown Kohoutek" (a version of his song "love in outer space") must be heard to be believed. Mr. Ra knew exactly what he wanted to achieve. With comparatively simple effects gear he arrived at unique creations. He was just a great musician.
One grade less over-the-top (in my opinion), and less threateningly energetic, is the recent two-CD re-release of Sun Ra's "Disco 3000". Fasten your safety-belt.
