All photographs by Jason Ano.

This Feature is Part of Complex's Skrillex "Alien Nation" Week

Most music artists have a photographer who's been with them since the beginning, documenting the days when no one knew who they were, when they got signed to a label, when they had their first shows, and what they do in their downtime. For Skrillex, that photographer is Jason Ano, who's seen his friend go from the offices of Atlantic to getting on MTV for the first time, chillin' with A$AP Rocky, and having a massive residency in Las Vegas.

As part of Complex's Skrillex "Alien Nation" Week, enjoy a photo tour of Skrillex's come-up.
