John Awesome and Nydia Hernandez were having a lovely engagement photo shoot in Holy Jim Canyon, California, when they encountered something unusual: a black metal band in the middle of the woods.

The band, Coldvoid, was also in the area shooting promo photos for its music, using the full moon on Sunday as its menacing backdrop.

“During the last part of the session, we noticed a few guys with some corpse paint makeup on sitting at a nearby bench blaring out some black metal music,” Awesome, 34, of Orange County, told ABC News. “We just randomly thought it would be a funny idea if we could get them to be a part of our engagement shoot. So we approached them and asked and they more than happy to accept! Super nice people. I seriously can't make this stuff up.”
