Maybe, you guys are just hung up on what you are seeing now in movies, which is NOT actually what the Disco era was like, but more of retro-Disco. If you weren't "there" in the 70's, then all you have is what the media today tells you it was like.
But, these look very much "Disco Era" pipes to me. No, not the Gibb boys prancing about, and actual discoteque flashy lights and feather boas. Discos rarely ever looked as if they'd have you believe in movies anyways. Saturday night Fever was NOT the way every disco looked.
But... the era of discos, was...
So, as an aesthetician, I'd say Georged is correct. The Scandinavia Craft style was emerging from the 60's "looks like it grew that way" style, into spheres connected to cylinders and squares style. Funky mix up geometry, guys playing with lathes, making those weird chair leg looking stems.
I don't think he meant pipes for Funky Town or Donna Summers.
That's just my take on it.
Funny though, a bunch of guys born after Nixon, telling us what they think the 70's was like, ha ha.
