Yeah, Pink Floyd and Rush are my top two(in that order).
I have In Absentia by Porcupine Tree, but I just can't seem to get into it.
No never listened to Close to the Edge. On the Yes Album I love "The Clap", but the rest dosen't do much for me. Another band I just don't get is Genesis. I tried to like them but it's boring. The only song that turns me on is Squonk.
I'm a big fan of ambient soundscapes and bluesy instrumentals, hence The Floyd obsession!
