Songs like Kashmir, No Quarter, etc. prove that the band was much more about studio depth, and songwriting, than actual chord technique. Zep were exceptionally proficient in studio, along with technical, which really set them apart from most mainstream bands from the 1970s, even good ones, that play very complex music by today's standards, but sound much older. I imagine for their time, Zeppelin sounded fairly future looking.

Which brings us to the original point, it's kind of unfair how prog is blandly stereotyped as anything that's complex.
