Skrillex is back with the original members of From First to Last, his former band, for the first time in 10 years. In a surprise release, the group dropped new single "Make War" Sunday night (Jan. 15), which happens to be Skrillex's birthday.

The rock track, out on OWSLA/Sumerian, is now available on Spotify and iTunes. Skrillex (aka Sonny Moore) co-wrote, produced and sings on "Make War."

He announced the release on Instagram and Twitter, posting artwork and a snippet of the song, which can be heard below.
