Greg Obis

Hi, my name is Greg and I’m an audio engineer in Chicago, IL. I own Chicago Mastering Service where I’ve mastered albums for artists on labels like Sub Pop, Matador, ANTI-, Car Park, Sacred Bones, Numero Group, Fire Talk, Winspear, Exploding in Sound and International Anthem to name a few. I track and mix records too. In addition to my studio work, I have traveled the country as a front of house engineer and tour manager for the likes of Jessica Pratt, Protomartyr, Yard Act, La Luz, and more. In my free time, I play guitar and sing in the band Stuck. This website showcases a limited discography of projects I’ve had the pleasure of working on. I would love to work on yours too!
