The critics love Run The Jewels. But some dude at SXSW, not so much.
The unidentified man charged the stage during the duo's set and threw a punch at El-P. Killer Mike tried to intercept him and then security forced the idiot off of the stage.
At that point he began scuffling with audience members. So Run The Jewel's team jumped down, with one of their peeps delivering a knee weakening blow to the stage invader's jaw. Then he gets the full beat down. Check out footage of the incident below.
Killer Mike also sent the unfortanate fellow off with a "fuck boy" chant.
