The day Metallica's over, i'm not going to put an ad looking for another band. I'll put my drumsticks on the shelf and there's 14 other things I wanna try. Metallica's the only band I've ever been and it's the only I ever wanna be in.

What Metallica always tries to do, as we go around and play a lot of the same cities, over and over again, year after year, is to give a different experience. We try to never play the same venues, or if we play indoors, we'll play outdoors, and all that type of stuff. It's always about just trying to do a different kind of experience.
