The UK's O2 chain of live venues has established a pretty cool YouTube channel, O2fancam - basically, they set cell phone camera footage of bands, shot by fans at the show, to live audio from that same performance. They've put together a couple of videos from Trivium's recent UK concerts that give a pretty good idea of what it's like to see them live right now. Here's a clip of them performing "In Waves" at the O2 Academy in Brixton on December 4:
And here's footage of them playing "Black" at the O2 Academy in Glasgow on December 6:
And finally, here's a clip of "Built to Fall," from the O2 Academy in Newcastle on December 7:
