Finally picked it up yesterday after wanting it for years and hearing the vinyl years ago. Anyway, was this record an influence on prog rock, metal and punk? I consider the first two because of course there are unusual, in this case, nonsensical lyrics and long instrumental sections, and I can also hear an almost prototype metal drumming style. The punk thing, well I read it in a newsgroup once that "Emergency!" was considered an influential record in punk circles so how valid that is I don't know. Anyway comparing "Spectrum" and the title cut to Trio Beyond's versions is an interesting thing, they both function very well, and differently on their own terms.
