Absolutely wonderful album and when the guys talk about how it was made, it just seems strange that it turned out as well as it did. In the Prog Rock Britannia documentary, Steve Howe and Bill Bruford comments on this. They talk about how they didn't know how to go from one musical theme to the other and someone would just get tasked with getting that done and they'd slap on various musical ideas that they had. It sounded like a patchwork, but the result and final feel of it sounds entirely cohesive to me. To me, it's an album that really balances the knife edge, with melodies solidifying, becoming more fluid, changing, all done at the perfect time in a way that really suits the songs.
It's easily my favourite Yes album
Still! It's not often people have made rock music as beautiful as this.
