That is some nerdy-ass prog rock.And I owned that album on vinyl in the very late 80s, when I was going through a huge "Yes" phase.
You know, I'm a huge fan of Prog and of Yes in particular, I own everyone of their albums and sill listen to them on fairly regular basis. But even I can't stomach Wakeman's solo stuff, that whole On Ice thing pretty much killed Prog.
Long live Prog Rock!
I have a grotesque fascination with 70s prog, for sure. You should check out the documentary "MOOG", which is about Robert Moog and the development of his synthesizer. There are a couple of interviews with Wakeman that are interesting, and has performances by folks like Keith Emerson (Aqua-Tarkus live ... talk about grotesquely fascinating). Streams on Netflix.
Wow! If you get a chance (it's kind of a long shot) you should look into Pete Sinfield's solo work (lyricist for early King Crimson)
