Marillion or Genesis. I love them both. Quite a few tracks on there I cannot stand and where is Echoes eh?
Although I like Prog, there is a shedload I cannot stand too and I'm quite picky when it comes to the genre. Oddly enough I have been working on a Prog comp for music 1990+ regarding epics but instead find myself just listening to it knowing that it won't get many listens (understandable with my tastes!).
Supper's Ready wins.
