The biggest music showcase in the world, SXSW, is currently taking place in Austin, Texas - but not every show is running smoothly.
Hip-hop duo Run the Jewels - aka rappers El-P and Killer Mike - were performing yesterday when a rather large man made his way on stage and attempted to punch El-P.
The man was removed by security and the gig continued, with NME reporting that RTJ led the crowd in a chant of 'f**k boy'.
Watch the footage of the incident and its aftermath below:
