This track is the second part of the SOFI Locked and Loaded EP that was just released today. Bring Out the Devil featuring Skrillex was produced by Kill the Noise and almost disappeared from the album entirely.
When Skrillex’s hard drive was stolen in Italy last year, this track was on there and it was unclear if they’d be able to ever release the song. But, Skrillex called Kill the Noise up and they were able to re-produce the original. More from MTV.
With SOFI on the Meowington’s Hax and Skrillex on the Mothership tour, the duo wasn’t able to get back together to finish the track until just recently.
