Deep down, they probably know it, too. On MTV, the only one worth watching was new bassist Robert Trujillo. Of course he's excited. To him, it's all new music. To his three bandmates, though, being Metallica might be starting to feel like more trouble than it's worth. That's how St. Anger sounds: resigned and more than a little self-doubting. They're dressing up in old and ill-fitting clothes, hoping metal fans won't be able to tell the difference. Well, we can.
