What could there be that is 'Celtic' about a metal band? When you get beyond the imagery, the swords, the pagan mysticism, or whatever persona the group puts out there, what will make the music 'Celtic' in nature? It's not even who the band members are.

What would connect the music to the Celts would be the lyrics, the musical instruments, when they are rooted in the Celtic tradition.

Electronica metal is no more Celtic than jazz. You can dress it up any way you want, but precious little of it will come close to anything 'Celtic'.
