In Italy there is one band called "Fratello Metallo", the singer is a franciscan friar (could anyone be more christian than him? ). They play classic heavy metal, talking about God, faith and life.
Of course, they are not a top band as Stryper for example, but the sound is good and the "singing friar" is unique for a metal band (it's also a bit funny and unusual at all).
