Max Williams has been holding a camera in his hand for the past 10 years since he began filming friends skateboarding. Through filming skating over the years, he began to realize how much he enjoyed framing shots and experimenting with cameras, lenses and different settings. Shortly there after he realized his appreciation for music and wanted to blend the two things together. Max attended Columbia College Chicago and interned at Sofar Sounds Chicago while he was there. This internship  gave him the opportunity to film live music. Early in his Junior Year at Columbia College Chicago he was offered the Head of Video Position at Sofar Sounds Chicago and has been their Head of Video since. Max graduated Columbia College Chicago with a Bachelors of Arts. He's had the opportunity to work with artists both in Sofar and outside of Sofar which has given him plenty of experience working video in the Music Industry.  "Part of working with me involves the experience between us. Instead of me just being a guy pointing a camera then saying bye, I like to make it a friendly and welcoming environment for those that work with me."
