Photos: This Is What You Look Like When You're Headbanging

During the summer of 2012, Danish photographer Jacob Ehrbahn traveled to a bunch of European metal festivals, like Copenhell and Wacken Open Air. Armed with a camera, Ehrbahn took fantastic photos of metal fans in the middle of doing what they do naturally- banging their damn heads. In fact, Ehrbahn took so many photos that he's got a book called Headbangers coming out on September 29!

So while we wait for that, let's take a peek at some of the photos therein, courtesy of It's Nice That.
