...that existed a couple of years ago. As for the world-music scene, I remember that those bands you mentioned did well and yes, that is a bit strange that the interest didn't go back to older bands.

However, isn't the world-music scene generally more into contemporary stuff whereas the ones more likely to check out, say, old music from Nigeria are more crate-diggers and stuff like that. Of course, old swedish rock/jazz-inspired folk (or even folk period)isn't really the same thing as afro-beat or whatever; I think that generally, old stuff from countries outside of america benefit from being "groovy" (or very rock-inspired or at least weird).
