Heavy metal bands are renowned for providing their fans with an intense concert experience.
But a new documentary has revealed how one band - GWAR - took things to the next level at their shows.
According to the doc, which is titled 'This Is GWAR', audiences could expect to be showered with fake blood, semen, and other bodily fluids.
The wildest part is that, for many concert-goers, this is one of the main draws of a GWAR concert.
In the doc (which was created and directed by Scott Barber), viewers are given a behind-the-scenes look at how the band came together.
Frontman David Brockie first started the craze of throwing disgusting things at his audience when he gave them pinatas filled with change, sweets - and cat poo.
Brockie eventually came together with artist Hunter Jackson to form the band GWAR in 1984. So beloved was the group by fans that even after Brockie passed away in 2014, they continued to perform to their adoring audiences.
While this may be the de facto story of GWAR's genesis, the band's website offers a more exciting version of how they came to be. The story "begins in the deepest reaches of outer space," and continues:
"Long ago, the beings who would become the rock band GWAR were part of an elite fighting force, the Scumdogs of the Universe. For eons, they served as thralls to a supreme being known only as the Master. But one by one, each future member of the band earned a glaring reputation for being an intergalactic f***-up. And so, they were banished, sent away on a fool’s errand to conquer an insignificant s***ball floating in a dark corner of the universe; the planet Earth."
Regardless of how they formed, one thing that the band has always been infamous for is their penchant for throwing blood and other bodily fluids at the audience.
Reportedly, one fan described on Twitter how they chose to wear a white t-shirt to GWAR's show so that they'd "have a better chance of getting covered in blood."
Another described how: "At a Gwar concert... they do battle with historical figures, monsters, politicians... and sometimes chop their heads off and spray the crowd with blood!"
"I had a wonderful time at the show," they added.
