I'm with those who could do without the growls, but everything else about this song kicks ass!
I've always thought that James would make an excellent addition to the ProgPower roster. In fact, I had a recent discussion with Orbweaver about this exact topic. Obviously, booking a band like Dream Theater for this festival would be way too costly, not to mention pointless. That said, there's no reason why Glenn couldn't get one of their numerous side projects. The same could be said of Iron Maiden. Who amongst this audience wouldn't kill to see Bruce Dickinson headline this show with his solo band? I think these possibilities are very feasible.
Stay metal. Never rust.
