Its stop motion Super 8 so there's no sound on the original movie. Its not a late 70s or early 80s vinyl because you'd hear vinyl noise.
Some of Mr. Scruff's tracks sound a lot likes this stuff. Sound a lot like The Orb as well. Tangerine Dream maybe? Tosca? Tycho, Luke Vibert, Aphex Twin his early stuff ...
Its probably just me, just sounds like something producers would sample making downtempo, I listen to a lot of ambient, lofi, downtempo, chill, etc.
The hats sounded like Fruity Loops stock hats or something. There's some flute sample in there. There's a real Rhodes or Hammond in there at the first track. The 2nd bit sounds like a real Arp is used for the bass, reverb tambourine, some drum loop ...
The moral of the story:
Röyksopp - Junior is a good fucking album.
