Most people seem to resent the controversial in music; they don't want their listening habits disturbed. They use music as a couch; they want to be pillowed on it, relaxed and consoled for the stress of daily living. But serious music was never meant to be used as a soporific. Contemporary music, especially, is created to wake you up, not put you to sleep. It is meant to stir and excite you, to move you--it may even exhaust you. But isn't that the kind of stimulation you go to the theater for or read a book for? Why make an exception for music?
