“You are a truly beautiful crowd,” said DJ Showtek as a throng of ripped alpha-bros erupted into violence during his set at the Sydney leg of Stereosonic. The fight, which will live on forever thanks to smartphone technology has gone viral after being posted on a handful of Facebook pages – the most notable being run by ‘bass’ artists the Stanton Warriors.

In the clip, 20 or so men unleash a barrage of devastating attacks on each other, despite some pretty brave efforts from festival security. (Organisers obviously didn’t realise that officials would stand out a lot more if they didn’t wear fluro.) Stereosonic fighting styles clearly cover multiple disciplines: some take inspiration from turn-of-the-century boxing whilst others clearly channel Mortal Kombat II characters.
