Today is Skrillex’s birthday — happy birthday, Skrillex! — and to celebrate, he’s reunited with his former band for the first time in 10 years. The EDM superstar fronted the emo band From First To Last for a few years in mid-2000s, and they’ve teamed up once again on a new surprise single called “Make War.” In addition to singing, Skrillex also co-wrote and produced the track, and you can hear it below.

“Make War” is out now on OWSLA/Sumerian.
