If Cellador's there, it can't be all lame
And concerning the previous mention of Bon Scott, I do agree that a vocalist like Bob Scott works in a band like AC/DC. I just expect differently from a PM band with the musical sense of Gamma Ray. Whereas AC/DC is basically a heavy blues band that would sound awkward with any kind of serious vocal melodies, harmonies, or anything remotely operatic, Gamma Ray sounds to me like a really good, melodic PM band musically with vocals that come straight out of left field from another genre that just don't live up to the promise of the rest of the music. Kai gave up singing duties in Helloween to a more melodically capable singer for a reason.
