This is as metal as it gets.

Two elderly men ditched their nursing home in Germany on Friday, and ended up at what's widely considered the world's largest heavy metal festival.

According to Deutsche Welle, police found the two runaways at Wacken Open Air, a colossal four-day annual music festival dubbed "the Metal Mecca," held in the small German village of Wacken.

After being alerted by the nursing home, authorities reportedly located the missing pair at a casual 3 a.m. at the festival — that's when the last stages finish up for the night, so these guys are pretty hardcore.

Police told the news service the men were "disoriented and dazed," when found. The party was officially over when police escorted the renegades back to their nursing home.

Whether or not the rebels intended to end up at Wacken Open Air has not been confirmed, but police spokeswoman Merle Neufeld reportedly told public broadcaster Norddeutscher Rundfunk, "They obviously liked the metal festival."

Exactly how far the music festival site is from the nursing home, and how exactly the two men ditched their home after hours is also yet to be reported, so you'd better believe our imaginations have run wild with theories of hot air balloons and underground tunnels.

Approximately 75,000 people attend Wacken each year, growing since its beginnings in 1990. On the lineup for Friday's festival were the likes of American death metal stalwarts Cannibal Corpse, Finnish melodic death metallers Children of Bodom and Nightwish, Swedish death metal icons In Flames, and progressive metal supergroup SOEN.

Suffice to say, the runaways would have themselves a double kick drum pedal-fuelled time.
