===Further proof that WikiPEDOS are morons=== 
 Like WikiPEDOS know anything about prog-rock. If you define "progressive rock" in the literal sense, i.e. rock music that's progressive, it becomes a term that's so vauge that it could encompass just about anything. Who cares if the man lovin' homos who are concerned with looking hip are offended if their favorite band is defined as prog, because the term is so offensive for homos who give a crap about looking hip. If my homophobia offends you, the boo-hoo. Gay homos and trannies are the scum of the Earth and they should all be rounded up into concentration camps and murdered. 
      I find it amusing that you jerks decided to completely blank the timeline because rawk music is such serious buisness that a timeline can't exist unless a perfect defenition of "prog-rock exists." Boo Hoo, people include their favorite bands in the list. 
      So I'll throw you estrogen poppin' butt pirate a bone; prog-rock is a style of music. Music does not need to be progressive or inovative to be defined as prog. As long as there is a focus on drama and pomp and a move away from short songs and conventional pop structures you got prog. If you listen to groups like Yes and Genesis you'll find that the previously listed attributes are the missing links that tie them together. Thus, "modern shit bands" like Mastadon are technically prog, as they meet the following criteria.
