get over yourself, how can YOU define what prog-rock is, or "Proper" Prog rock, people interperate what they think is prog, its not a look at how big my e-peen is im the god of prog-rock.
oh dear. Thats what trying to be helpful gets you on the forums. Back to silent membership it is then. I'd suggest you need a complex understanding of music to get to grips with this genre rather than a big a peen or whatever it is you have, seeing as the artists themselves are for the most part phenomenal musicians who are classically trained I think it is quite pertinent to try and interpret {interperate, nice} their music analytically and see it as a proper music form: ie. applying classical understanding of music to better understand their music.
Cant believe your command of english is so poor that you'd think I was giving or attempting to give a definitive list of prog. Rather, it is just a list of acclaimed progressive artists, who, for someone who might just not know much about the genre would find useful and accessible.
