I'm looking for more rock bands... Help?

I've been a die-hard Disturbed fan ever since i heard "Down With The Sickness" Now I know every single song they've made by heart, and all the band members names, ages, and religions.. lol. David Draiman is gorgeous, has a distinct voice, and his view on life is absolutely amazing. he's so intelligent. they sing about things that matter, like government issues, religion, etc. The way they get their messages and beliefs out is just beautiful.
