They are boring live. It is a bland, no energy performance. When I last saw them little over a month ago with War of Ages and Arsis (who killed the show, btw), the vocalist for All Shall Perish wore a Nacho Libre mask the entire time. I suppose that means little to nothing, but the rest of the band has zero stage prescence, and were possibly the worst band on the bill. I guess you will have to see for yourself. And believe me, I actually was looking forward to seeing ASP.
However, War of Ages and Terror should be rockin!
