Uranium? Are you guys joking? Uranium almost ONLY plays nu metal, they very rarely play a band besides Korn, Disturbed (their favorite band), Mudvayne (their second favorite band), Linkin Park, or that ilk.
Headbanger's Ball plays a lot of great shit like Neurosis, Mastodon, Cattle Decapitation, Pig Destroyer, Opeth etc.
But the best is Extreme Rock which plays even better shit like Neurosis (again), Killing Joke, Poison the Well, From Autumn to Ashes, Underoath, A Static Lullaby (sadly by far their worst song), etc.
Also, Mnemic are NOT nu metal and they are rather good. They are industrial metal (just like Static X, bitch).
