“It was a month and a half of non-stop work – barely sleeping, barely doing anything but just painting. It was an epic job for me.

There was a lot of back and forth.” Los Angeles street artist, El Mac, on the process of making No Doubt’s cover art for their new album. According to Billboard, the “four custom portraits were photographed and then rendered manually into paintings.”
