What would music be like if PROG never happened?

I think we may be talking about two different things? I am talking more about the reception of the music by the listeners, not what the artists themselves think about their music or other bands. Robert Fripp, for example, doesn't consider King Crimson a prog band, is generally hostile to the term, and also seems generally dismissive of other British prog bands (actually, one doesn't even have to venture outside of Great Britain to see prog bands dismissive of one another). Yet at the end of the day King Crimson is still considered to be a prog rock band nonetheless by almost everyone (except the extremely silly or utmost Fripp-fanboys, IMO), because of the qualities and context of their music.

Now, granted, Krautrock bands, obviously, are more disputable than King Crimson is (Crimson is a special case as an "archetypal" prog rock band; that is, they are one of those bands viewed as practically synonymous with the genre)--these things are largely relative and individualistically determined, and guided over time by the consensus of fans. I recognize that there are those who consider Krautrock entirely separate from the 'prog rock' rubric, even though I personally disagree with that position (I am more liberally-minded in my conception of 'prog', tending more to see the similarities than differences between the bands). Like Pashimina said, it IS kind of like a Wenn diagram. They are not entirely independent (relatively speaking) from each other in a categorization kind of way. Most prog rock forums feel free to discuss Kruatrock bands...why? well, obviously, because on a grand scale (which is what the labeling/categorization is addressing), the qualities of, say, Yes and Can are on the whole are much more similar than comparing either one of them to, say, Britney Spears or The Flying Burrito Brothers or Bruce Springsteen or Run D.M.C. On a more specific scale, of course, there is a recognition that these bands are not entirely overlapping or necessarily closely related either--that is, it would be utterly ridiculous to expect someone to like Yes just because they like Can (or vice-versa), and indeed not everybody does. There are differences in the two bands' stylizations, musical influences, etc. Again, one doesn't even have to make it Krautrock versus British prog rock distinction. I love Yes but dislike the Henry Cow I've heard. I love mid 70s Popol Vuh but was not at all into the first two Kraftwerk albums (or the first Popol Vuh album! :) ).

Wallenstein, Grobschnit, Eloy - they are all terrible and they are all pretty much prog rock. Terribleness being a major sign of whether or not band is prog or not, in my experience.

I don't agree with this--I think it is limited to define or characterize a genre, label, or other similar concept (i.e., a way of categorizing the surface qualities of music in a way that is reasonable) based primarily on personal taste. Note that this is what a lot of zealous prog rock fans do, except they do exactly the opposite: "This music is good, therefore I like it, therefore...it's Prog!" or along similar lines "This music sucks." Why? "Because it's rap." (i.e., Rap as an entire genre is defined/recognized as "bad music" or "not REAL music" or "music I don't like"). [Sorry, Geir! :) ]

Camel.

personally, Pink Floyd always transcended the prog mantle, for me. not just because of where they went but how they came to it- Syd era(pop oriented, sometimes insane, sometimes boring jams)- intro Gilmour- delving into the song structures(MORE structure)- Waters comandeers- we get Dark Side of the Moon. and the rest just falls into place so neatly.
where as bands like Genesis just don't hold up quite as well. ELP, KC, Yes, and the lot have a song here, a song there but never live up to thier ideals. but, that's my opinion and i'm apt to being wrong.

and yes, prog fans are almost worse than Dave Mathews band/Phish fans.
they'll lap it up, not matter what and call it divine.

Wow, what a generalisation. I must have imagined all those arguments on prog internet forums.

hey, i do what i can with what i have...hehe!

like it was stated above, prog fans tend to be as uber-elitist as the next subgenre. it's the willingness to enjoy vast wankery, meandering bilppy bloops, and 10 minute synth solos, and twirling drum kit antics that made me generalize so.

note- i did say ALMOST.

and yes, i'm not excluded.
it's just hard to debate someone with a straight face when they keep using early Genesis, or Yes as a reference point of any kind.
and Peter Gabriel. for the love of gawd, he's worse than Don Henley!

that wouldn't be all bad...
i could learn to live with that.

No industrial dance beats-
nah! somebody would've come up with it...
hmmm, this begets the question-
How would the mid 90's Nu-Metal have come about without Faith No More or Ministry?

and...
Did cocaine inspire all 80's mainstream music/movies?
i say- YES.

Ryuchi Sakamoto to thread!

and they should all bring samurai swords.

Marshal Jefferson's favorite band was (is?) YES. And Larry Heard dug them, too. The connections between YES + Chicago house are there. Somewhere.
