Germany and heavy metal....like a fart

Not a scientific analysis, but does it seem like all German guitar players are into metal and pretty darn good at it?
This is a friend of mine, Walter Grund. We have co-written and recorded a few songs and I knew he liked metal but never heard him play any. He got a job creating background music for a film, and in only 3 or 4 days came up with an entire album of metal instrumentals.
Like it was as easy as drinking water for him....or as the Polish say, "like a fart"
