Duo played second-ever live show Wednesday night.

LOS ANGELES — On Wednesday night, Travis Barker and DJ A-Trak played their second-ever public show together — and although the set was quick, it did not disappoint, featuring guest spots from [artist id="961130"]Lil Jon[/artist], [artist id="3066140"]Kid Cudi[/artist] and [artist id="2990953"]Kid Sister[/artist].

Travis Barker, DJ A-Trak Play Hollywood

Performing in front of a sold-out crowd at Hollywood's Roxy Theatre, the duo hit the ground running the minute they took to the stage. With a set that lasted a little under an hour, the duo treated fans to a medley of songs that included remixes by A-Trak (who also serves as Kanye West's concert DJ), Barker's own remixes and new material.

Though there wasn't any interaction with the fans, the crowd didn't seem to mind. Instead they stood and watched in awe as Barker and A-Trak opened the show with Jay-Z's "99 Problems" and continued to please the crowd with remixes of Nas' "Made You Look," Kanye's "Stronger" and Snoop Dogg's "I Wanna Rock."

And just as the energy was peaking, fans were treated to a guest appearance by Lil Jon, who took to the stage with his signature sunglasses halfway into the set and performed his song "Outta Your Mind."But as just as quickly as he appeared on the stage he was gone, teasing fans and leaving them wanting more.

As the night went on Travis Barker and A-Trak continued to perform an array of tunes, adding a little more of a rock feel to the show with Rage Against the Machine's "Bulls on Parade,"

the Beastie Boys' "Sabotage" and the Yeah Yeah Yeahs' "Heads Will Roll." Each song lasted for only a few minutes before spilling into the next. The set then transitioned into more dance-oriented material, with songs like Prodigy's "Smack My Bitch Up" and Daft Punk's "Robot Rock."

Not surprisingly, the set ended with a bang: opening act Kid Sister returned to the stage, with Barker playing drums and A-Trak spinning behind her. Wearing '80s-inspired attire, she pumped up the crowd with some booty-shaking moves while performing her hit "Pro Nails."

But when Kid Cudi took the stage, the crowd exploded. Performing "Pursuit of Happiness," fans sang along at the top of their lungs while Cudi jumped around the entire stage, high-fiving fans lucky enough to be standing in front.

The show ended just shy of midnight, with A-Trak waving to and thanking the crowd and Travis Barker handing his drums sticks off to a screaming fan before walking off stage. As fans scattered to the exit doors, VIPs headed backstage — including Amber Rose sans Kanye West.
