Originally issued as El Saturn 101679, recorded on 10/16/79, this incredible album is 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. On Jupiter uses more than the usual amount of post recording processing and mixing, nudging up to the jazz-rock/disco music of its time, but not getting too close. These are still eccentric, expanded, lurching musical beasts. And it's nice to hear the oboe and bassoon -- so often lost on the live concert mixes -- so prominent here. The playing is great, as ever.

This release along with Sleeping Beauty are two of the more accessible Ra releases and mark a rare experiment in quasi popularity by the band. They are both also, at present, collectors' items.
