I wouldn't call myself a *huge* fan, but I do have the album with "Blacker Than the Sun" on it (SKELETOR SKELETRON or something like that might be the name of it?), and I do really like that one. But I've heard it's not really a good representation of their usual sound?
Still, I do like that one, FWIW.
