You should be. He's better acoustic than he is doing metal shows. His voice sounds better than it does on anything else.
IF the world tour gets any US dates (not looking likely at present, but still), you really should put aside that silly "dur, metalz unplugged sucks" thing most metal fans don't seem to be able to get away from, and go see him. And buy the new acoustic EP. The version of 'Sign of The Cross' is worth it on its own.
