Mmmmm! I like the modern-esque second half. 'IWHWF' and 'It Can Happen' are underated for sure. And Dreamtime, I wanted it too but I'm thinking that without an orchestra it might sound a bit... flat?
By "deep" tracks do you mean lyrically or the sound, or just with the general feel? I guess a lot of those qualify for both anyway.
And I like some world music, but The Ladder was drowned in it. It's not really that suitable for a British rock band. I suppose some people make it work better than others, like Moraz with his Brazilian stuff, and Paul Simon (who is now so associated with those African (?) rhythms that it would be weird if he didn't do song in that style). To me, Yes are only amazing when they rock out with western instruments.
