Not quite a supergroup, but close...:
One half of Psycho White is Travis Barker, best known for his role as the drummer for Blink-182, but also holding much respect for his work with the Transplants, Box Car Racer, a stint with the Aquabats and countless hip hop collaborations. He's no stranger to the Warped Tour, nor is other half of the duo - Yelawolf, a rapper who has spent his own time bringing hip hop to the Warped Stages with a frenzied style as fitting for the Warped mosh pits as many of the heavier bands.
In September of 2012, the band launched their first single, "Push Em," as a free download on various sites. You can still snag it for free, and the link is below. Featuring Yelawolf's lyrics backing vocals from Skinhead Rob (a co-founder of the Transplants with cameos on records by Rancid and Lars Frederiksen and the Bastards) and Tim Armstrong, the whole track is propelled by a manic energy with staccato beats and a frenzy that is pure punk rock. There's a beat that would have been familiar on the most frantic industrial bands of the '90s, tight lyricism with a building aggression, booming bass and a chorus that translates as well to the circle pit as it does to the dance club.
Perhaps that's the most exciting part of their entire Psycho White EP, which was released on November 13, 2012, debuting at #49 on the Billboard 200; it's the way that punk energy perfectly melds with hip hop beats, creating this mash up that elevates both sounds, in the way that bands like TRC and Enter Shikari combine to create something exciting energetic and sometimes danceable, standing opposite to the way that crunk core bands like brokeNCYDE most decidedly do not. Live drumbeats blend with programmed loops, and the tracks don't ever feel like they're being contained by any genre requirements or limitations.
The EP was released on LaSalle records, a division of Atlantic, and itself another sign of Barker's influence on music. Founded by Barker in 2004, the site has been the home for Barker's releases as well as anything from a varied sound that he has liked. Barker is also the founder of Famous Stars and Straps, a clothing company launched in 1999 that, like Barker, is heavily influenced by styles originating in both the punk and hip hop scenes.
