"What is Progressive Rock?"
To be honest with you, I would stay away from that website's definition of the music. Theirs is becoming an academic definition that is senseless and only 3 bands fit the mold, which is the excuse for them to say that KC/ELP/Genesis are the progressive bands and the rest is not and then create sub-divisions to make room for everyone else.
There is no care to understand and see, that these scenes existed in orhter places in the world. So by their definition, LA, SF, NY, Munich, Paris, Rio ... no other place in the world can have, or be "progressive" and there are many bands that went on to do a hell of a lot more -- and way better -- than those bands in London, that pretty much became media and hit music darlings for the record companies, although Robert Fripp revolted really hard.
Progressive has become a term to simply tell you ... longer cut, louder, noisier, more effects, and wierd lyrics, or strange sounds! And making sure they use the "loudness" techniques (DT), and so on ... and has very little to do with "progressive" any more than it does the Friday Night Lounge Lizard favorites that we love to listen to.
PA thinks that because Neil Peart read Ayn Rand that the music they put together is "progressive" ... but seeing someone use Burroughs on stage with his real voice (Lori Anderson) as lyrics ... is NOT progressive ... which kinda tells you how much music those folks listend to ... only the hits! ... sorry ... not qualified!
