originally released on saturn records in 1979, these are both studio recordings by the large ra ensemble (including electric guitar and electric bass) and, for the most part, feature the first recordings of the titles included on them (though most were played live a few months earlier). these two releases belong together, since they were recorded and released in close proximity and are both long, groove-based, pieces that range from proto-disco to relaxed groove-driven pieces in which electric piano, guitar and bass function as a ground on which a parade of events drift in and out; 'sleeping beauty' is a chaotic, swirling masterpiece with lots of effects added to the instruments and an interesting mix. 'on jupiter' likewise 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. but these 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.
