I'm prolly the only one here but....Genesis?

 

Let's go step by Step

 

1.- Yes is one of the most accessible Prog bands (I remember Micky, one of the most fanatic Yes fans, calling them Pop Prog), their early material is basicallñy ROCK, simple and plain, they make a final product and overlay the arrangements, take the Organ solo of Close to the Edge and it's a boring track, but you add it and it's one of the best moments in Prog....But you can play the song with or without keyboards and still be coherent.

 

While the roots of Yes are in Beatles, Moody Blues and bands as Simon and Garfunkel,. the roots of Genesis can be traced diirectly to Prog, in other words to In the Court of the Crimson King, as a fact, their sound changed radically when Peter took a copy of In the Court to the first Trespass sessions.

 

Yes never broke with the past, still there are echoes of their first simpler albums in all their discography, you find nothing pre-Trespass in Prog Genesis.

 

2.- Genesis was an integral product, if you take a keyboard note from Musical Box, you make it unlistenable, you destroy the logic, the coherence. In Yes the keyboards are the cherry on the top of the cake, in Genesis the interplay between guitar and keyboards is the whole cake.

 

3.- Relayer is as complex as The Lamb, if not less.

 

4.- Siberian Khatru is a Rock track with complex arrangements, nothing more, while Fountain of Salmacis or Giant Hogweed are a compact work from which you can't remove anything.

 

My two cents
