Some off the top of my head:
>GenesisFoxtrot and The Lamb Lies Down on Broadway are my favorites, but you're good with everything from Trespass to Wind and Wuthering. I'd avoid the 80's stuff, there are some proggy tracks on them, like the Domino suite, but most of it is AOR and too heavy on drum machines for my taste. I do like most of We Can't Dance and Calling All Stations THOVGH
>ELPELP, Tarkus, Trilogy, Brain Salad Surgery
>YesThe Yes Album, Fragile, Close to the Edge, Tales from Topographic Oceans, Relayer, Drama. The Ladder was pretty good too.
>Jethro TullAqualung, Thick as a Brick, A Passion Play
