Korn treated fans to a first-ever live performance of "Rotting in Vain" at July's Chicago Open Air Festival, and now the nu-metal band has shared the professionally shot footage from the event. To switch things up from the typical concert footage, the clip starts from behind the band members in dramatic slow motion. Then, as soon as that wild guitar riff kicks in, the vibe shifts from mellow to thrashing. 

A sea of fans with their hand horns in the hair, Korn rocking out on stage, the toxic-looking purple lights and lead singer Jonathan Davis' awesome silver microphone stand are all thrown in. If you didn't get a chance to see this debut performance, the concert video will make you feel like you're right in the mix. The only bummer is that the audio is from the studio version, not live.

"Rotting in Vain," as well as new single "Insane," is featured on Korn's forthcoming album The Serenity of Suffering (out Oct. 21). Below, watch guitarist Brian "Head" Welch discuss his struggles with past drug addiction:
