Skrillex aka Sonny Moore has been "officially" back in From First to Last for over a year. They "leaked" a song last year, and today made their first official single release for the track "Surrender."
I wouldn't exactly call it metal, but it has some hardness, but is overall catchy, somewhat poppy tune. Take a listen.

No word on if this is part of a full album, or a tour or anything. So, From First To Last fans can just enjoy this one for now.
