I tried their album with the big IV on the cover, not gonna bother to remember the unreasonably long title. It was pretty good, I didn't like the production of the guitars and thought that this would improve live, it kind of did. But there was just something lacking about their live show. The performance was often sloppy (the band had trouble with time changes, the transition to the fast section of Heaven and Hell was a nightmare) and the energy just wasn't really there. Excluding the singer, who seemed really excited to be on stage. It was for the most part an unremarkable show, as compared to Dream Theater in 2010, who were almost just as awesome as Maiden. (And there's no bias there, I knew nothing by Dream Theater at the time. In fact it was that concert that drove me to check them out.)
