Do you know of any ROCK stars that are actually nice/normal in interviews or when they're not performing?

Are there any rock stars who separate the music from the lifestyle? I mean most people who play rock music all act the same way (angry, "i dont care", "fck you all" attitude). Even in interviews (which is weird because obviously they agreed to be interviewed which means they care). I was just wondering if there were people who play Rock music but were relatively normal/nice in person
