This documentary focuses on British progressive rock of the "classical" age of progressive rock, which is only fitting, because progressive rock was born in England, made world famous by British bands, and (apologies to all the rest) the cream of progressive rock, at least in its heyday, was created by British bands. Yes, there are prog bands making good music today, and they're not all (or even mostly) British, but I'm sorry to say, they will never reach the peak of the classic era, either in fame or in creativity.
