Why not more ratings for Gentle Giant albums?

I never said it's either/or.  But there's some music that does not lose its emotional resonance in the midst of all the complexity.  And then some whose appeal necessarily has to be explained in technical terms, which is what we are doing here with regard to GG and a lot of other prog too slots in this second category.  Why should we have to explain the appeal of GG in terms of the brilliance of their changes or the versatility of the musicians?  These are more academic aspects; music can be emotionally resonant without unthinkable changes or without five multi-instrumentalists.  Yes, as you said, it necessarily involves listening carefully to the music to appreciate these aspects but additionally also an interest in musical concept rather than emotions alone.  Most people who do like music also listen to it more for the emotions it conveys rather than concept.  I can understand why that would leave them disappointed sometimes when it comes to prog.  We ignore the somewhat goofy aspects of GG (like the synth break in Cry for Everyone) because we focus on the sheer brilliance with which the notes have been developed, mathematically.  That is not something that interests everyone, which limits the appeal of prog.  

That's a good phrase - Robin Hood vibes.  There are parts that sound like music set to Tom & Jerry cartoons, esp the T&J kids series (which was actually made much later I think).  Yeah, I can see why that would be a huge turn off at least initially for listeners.  You don't have to get over anything in particular to listen to Yes or the first Crimson album.  I think it's great that this forum and others are keeping Gentle Giant's music alive to the extent they have, else this music would have likely faded out of memory.  

Thanks. 

and I think you're right about GG. They would most likely have been forgotten in the experimental rock files from the 70s, had it not been for places like this.

I also agree about the parallel to KC and Yes - unlike them GG never really went and made an "easy-to-get-into" album in their prime.Sure one could always go for the lacklustre pop releases, but then again why even bother? Every classic GG album features Robin Hood in full flex, now whether that's done through impossible vocal harmonies, Medieval instrumentation or clandestine bow and arrow tournaments - it's always there. Three Friends is perhaps the easiest of theirs to get into methinks, but I gather that's down to the symphonic qualities of it.
