*sigh* I'm fairly sure the Trivium thread was on the first page of GMD, if not, the second. You didn't look hard enough.
Start with Shogun. There you go. It's their second best album after Ascendency, but it's the best place to start.
Also, I haven't heard anything about bags of piss being thrown at them, but with the immaturity of some concert-goers, I wouldn't be surprised.
