I don't really like System of a Down, outside of Nuguns.
Korn? Not the biggest Korn fan, but I thought that they were really fun live.
I think Linkin Park is very talented, and has done some innovative stuff.
Talented? Currently? These are mostly still recording:
Distrubed (personal favorite)
Drowning Pool (Bummer death there),
Damage Plan (another bummer, Dimebag was a genius)
Perfect Circle (another Maynard from Tool project)
Muse (massive talent)
Audio Slave (old school feel)
Rage Against the Machine (yes, they are idiots, I know)
Evenessence (very pretty voice)
Live (just classic stuff)
Shinedown (okay gun guys, listen to .45 and tell me it isn't awesome)
Kasabian (I've recently taken a liking to this band)
TRUSTcompany (nice guys in person)
Dave Matthews (yes, sometimes I don't want to bang my head)
Radiohead (possibly the most interesting and fun live show I've been to)
Rob Zombie (the MAN)
Breaking Benjamin (pretty talented)
Slipknot (when you really want to jump up and down and smash stuff)
Papa Roach (getting away with murder is a favorite)
Saliva (I grin stupidly every time I hear Click, Click, Boom)
Rollins Band - Black Flag (because Henry Rollins yelling at stuff is great)
Cyprus Hill (Good stuff, esp Rock Super Star)
Lacuna Coil (from Italy, reminds me of Evenessence)
Eve 6 (lyrically creative)
Gorillaz (fun rap/dance/punk)
Godsmack (good guitar work)
CKY (fun rock)
Anthrax (Scott Ian on guitar)
Rush (still recording, very good)
Rammstein (oh you know you like getting yelled at in German)
Killswitch Engage
Ill Nino
Hot Hot Heat
Taproot
Three Days Grace
Deftones
Tenacious D
Black Eye Peas
Outkast
Life of Agony
Black Label Society
Powerman 5000
Black Sabbath (okay, not current, but sometimes you just need to listen to War Pigs)
Mudvayne
Nevermore
Chevelle
Foo Fighters
Ra
Okay, that's what I can think of right now. There are lots of talented bands working right now. Now what their politics are? I have no idea, and on most of them I would rather not know.
