The other day I was thinking this, and ironically maybe I'm just musically dumb at times I find most common/poplar prog rock bands aren't really anything musical theory crazy, other than bands that may time signature change and some other elements in other songs, they all seemed to have some form of radio-rock element. I love YES don't get me wrong but I feel like if you insult or make a point hardcore prog fans on other forms get upset and if you look on any prog rock form or subreddit you'll see stuff like "It's too advance" or "That band is complicated enough for me..." it's almost like I think they oblivious to their own thoughts... This can be found in any genre of course Jazz has some gatekeeping at times but in all genre there's awesome people as well!Lots of guys here think of Prog Rock in a pretty arrogant way.
