Rumble. Just rumble.

So rumble, young musicians, rumble. Open your ears, and open your heart. Don’t take yourself too seriously, and take yourself as seriously as death itself. Don’t worry, and worry your ass off. Have unclad confidence, but then doubt. It keeps you awake and alert. Believe you are the baddest ass in town, and that you suck. It keeps you honest. Be able to keep two completely contradictory ideas alive and well inside of your heart and head at all times. If it doesn’t drive you crazy, it will make you strong. And stay hard, stay hungry, and stay alive. And when you walk onstage tonight, to bring the noise, treat it like that’s all we have. And then remember: It’s only rock and roll.
