hmmm just tried listening to some dream theater on youtube..
i actually don't want to listen to any more of it for fear that it may ruin my taste in music and skill as a guitar player,
it sounds like what me and my friends come up with improvising on the guitar when we think "what would sound cool to other people and sound like we possess complexity?"
i guarantee they are just building together bits and pieces of riffs they heard other bands play, and constructing them in a way that sounds original
