What are some really good, heavy, throw a brick in your face, metal bands?

I don't like screamo or grindcore. Keep it low on the grunting, and stick with the bands that sing and scream at a good equal. No black metal, or metal core, i just want more, good, old fashion metal in my iTunes.

Tool, anyone?
Alter Bridge, maybe?
A bit of John Mayer?
Some beethoven sounds delightful, as well.
