A mixture of live recording and studio post-production, 'On Jupiter' sounds unique to any other album Sun Ra made. The arkestra reflects a disco pulse right back on itself, and delivers one of the most cohesive albums of their career. The title track is a masterpiece of gentle atonal harmony, while 'UFO' pushes along at a cracking disco-ish pace with fierce brass and spacey dub effects. This a timeless Ra classic.
