My favourite, too. Apparently they spent years and years on that thing. Perhaps partially through a lack of material (one of the best songs is a cover of a track by the French Residents-alike, Ptose), but obviously also because they were on some perfection trip. I think it may have temporarily busted their relationship, though. There's a mini-doc on youtube about them doing a soundtrack to a fairly recent movie where they seemed fairly cool with each other. https://www.youtube.com/watch?v=aClQWio3ngM
