I'm not really into Trivium, but * me they are amazing live. The way they worked the crowd was very different to In Flames last night; it wasn't forced, just four guys enjoying themselves and the connection with the crowd. Even though what they do isn't really my thing, I can still appreciate how good they are as musicians and the effort they put in; they've toured here 14 times now.
I'm not into Trivium either but I'd imagine they would be pretty intense live.
