Why is Captain Beefheart so freaky?

My four-year-old daughter asked me a few days ago: "Why is Captain Beefheart so freaky?" I said: some artists think differently - their brains work in a different way than other people; they put thoughts together that other people wouldn't. I could see her thinking about this. Since then, she's mentioned it once or twice. I wonder what will come out of this? I wonder if listening to C.B. from such a young age can have an impact on brain chemistry? Kind of like listening to Mozart, but more... freaky.
