Mushroomhead, Killswitch Engage, Throwdown, Slayer, Stone Sour (Corey Taylor and Jim Root from Slipknot's other band), Pantera, Korn, Danzig, Opeth, Devildriver, Fear Factory, Helmet, American Head Charge, Disturbed, System of a Down, Corrosion of Conformity, Lamb of God, The Black Dahlia Murder, Down, Sepultura, Soulfly, Otep, etc... that's just a few bands I like. There are tons more.
I listen to most of those, there are a few I don't kno. I dig Otep and Stone Sour for sure. I also like All that Remains, Bleeding Through, Godflesh, Megahertz, Dope, and In Flames. Opiate For The Masses is decent too.
