The clip itself is from a 'techno' documentary, which also featured a number of other electronic groups of the era (Prodigy and The Orb both springs to mind, possibly Leftfield as well). I had planned to go through the video at some point, as there's a few other places where both Rick and Karl makes some comments about their music, but that was years ago and I've subsequently lost the source file.

Clips from Björk's own concert at the same festival, was also featured as part of a 2-hour show from that year's festival that ran on Danish television, so there's always the chance they might have some more in their archives.
