I feel like throwing Rammstein in here. Not a lot going on for guitar players and a bit off from Pantera, but it works. It shouldn't work at all, but for whatever reason it does. A lot of basic groove E-string chugging with simple keyboard lines for grooves, and I'm pretty sure German was God's intended language for metal.
They also appear to have some knack for making good videos and putting on good shows.
