German influences for the fanfic

So i started to get back into listening to German metal, so I kind of have a fanfic theme for one of my stories.
The Rainbooms have their own style of music but I want to see how it would turn out if a character has a band that does German nu metal, something that has not been seen or done in the Equestria Girls universe. Come check out my story Zeichen und Wunder, give it a read and see what you think.
