To celebrate the 10th anniversary of the Agenda apparel convention last night, promoters threw an industry-only party at Lush Lounge in Long Beach, CA featuring sets from Travis Barker and Yelawolf as Psycho White, as well as an opening set by Beastie Boys DJ Mix Master Mike. Psycho White is comprised of Travis Barker and Alabama rapper Yelawolf. The duo released their debut self-titled EP in November and have played a number of shows since, notorious for being a little rowdy.

As seen in the video above, during the middle of Yelawolf’s song “Marijuana” (around the :45 mark) an over-zealous fan jumps on stage and raises his fists in victory. After a failed stage dive, the fan gets pushed back on, invading Yelawolf’s personal space. The rapper then cocked back and threw a solid blow, sending the wobbly-legged drunkard into the arms of an awaiting security guard.

Word on the street is that Dr. Yelawolf is now available for discount facial reconstruction. Only drunks need apply.

The Psycho White EP is now available.
