You didn't smoke up before "Forbidden Zone", did you, Billy Dude? Your description actually makes me wanna watch it (has been awhile).
Yeah, Stereolab are pretty samey but they have a nice sound and consistently good material so who cares? "Mars" is my favorite album partly because of subtly building songs like "3 Longers Later" and because it straddles the line between the early VU period and the later krautrock period. Like someone else said, their later albums have richer, more electronic heavy production. I don't agree that their singles comps are the best stuff though, except that "Refried Ectoplasm" probably ranks up there with their better albums.
