Cover art for [The Wall Concept] lyrics by Pink Floyd

Oh by the way, this is also for The Wall the movie, if you care.

A good friend of mine (and a major die hard Pink Floyd fan) told me that Roger Waters started up the concept behind The Wall, when he was thinking about how much he hates his generic fans. He was talking about how the only reason they come to the concerts is because they want to see someone famous on stage, or something to that point. Then he went on to say that it wouldn't really matter who was on stage, it could be Pink Floyd, or anyone, it didn't make a difference. They weren't there for the music, they were there to see famous people. And then he thought it would be cool to build a wall between him and the "fans" so that they could only hear the music, and be forced to love the music for what it is. So really... our Wall was built because Roger Waters is a dick ^_^

There are a lot of concepts in the movie I could discuss too, but it was so long and complicated, I think I'll just wait for other people to comment.
