Rock musicians are very interesting people. You can reproach them with many things but you can never say they are boring. In addition, they are often very intelligent.
For example Marilyn Manson, the most controversial singer I have ever listened to, looking horrible and thus behaving on the stage is mild like a lamb when giving an interview. He based his philosophy on such different schools as: Christianity, Satanism, Decadentism or Freudism. Being a satanic reverend, in his lyrics, he fights all violence affairs on TV, calls people to real faith, blames hypocrites and weapon producers.
Indeed, rock musicians are very interesting people.
