Sorry I know that some people are really into this album but I just didn't get it. While Tangerine Dream abandoned the concept of rock and just had fun making weird synth sounds, Yes and ELP not only wanted to retain the status of rock musicians, they promoted of the idea of the "concept album" a dreadful idea that almost killed rock. Tales from Topographic Ocean is too meandering to pass as rock but yet annoying enough that it can't quietly filed under ambient. If you see this in your parent's lp collection, don't ask. You don't want to know.
