The "Celestial Body Mix" of "Oasis" is the dance floor version. The urgent early mood created by its chord stabs gives way to something brighter and more open, like reaching a clearing in a jungle. James uses pads, keys and historically accurate drum breaks to arrive at a feeling of bliss. The "Erotikk Mix" decreases the tempo and increases the humidity. The non-musical aspects—trickling water, bird calls, sexual groans—fit both the mood and the time period James is going for.
"Mating Rituals Of The Eastern Suburbs" leaves Italy and heads to Australia: the track is apparently devoted to "the humble inhabitants of the Burwood suburb of Melbourne." I can't figure out the social commentary James seems to be making (we hear the voices of these "inhabitants" at the track's end), but I can tell you there's a sort of primal energy here, with chants and rattling percussion that aren't a million miles from The Sugarhill Gang's "Apache." Oasis & A Time is mostly an exercise in mimicry, but it's an impressive one.
