Hmmm...I'd say...

Black Sabbath!
Marilyn Manson!!! (PLEASE??!!)
AC/DC
Led Zeppelin
Metallica

Other bands that would be freaking amazing:
Stone Temple Pilots
Alice Cooper
Deep Purple
Godsmack
Lamb of God
Static-X
Korn
Van Halen
Megadeth
Tool
Nine Inch Nails
Opeth

And here's the long-shot: Aerosmith

We need to get more real metal back in here...instead of this hardcore s*** (i.e Hatebreed). We need to party as if metal just came out.

Oh, and, free tickets please??
