Whatever it was that sparked Sun Ra to investigate the funk between 1976 and 1979, we should all be thankful that he did. Having explored dreamy languid rhythms before - with off-key arrangements and chants on records like New Steps, Lanquidity, Of Mythic Worlds, and Disco 3000 - On Jupiter sees Sun Ra really flexing his funk muscles, stretching the group like a rubber band. Blissful flanged guitar threads its way throughout the title track, and Ra throws up piano chords and vamps all over an upfront, but fragmented bass pulse. But while the Arkestra might be getting their oblique grind on in the rhythm section, the music still carries those cosmic messages from the stars. Just as Ra transplanted the big band traditions of Fletcher Henderson and Duke Ellington into his own cosmic vision, here he takes the back beat of funk and disco, and teleports it into another dimension.
