Rob Duffy Rob is an LA native recording engineer and musician who started at Kingsize as an intern in early 2015 and now serves as session manager and one of our house engineers. His musical interests and projects are eclectic and wide-reaching, to say the least. One day he’ll be mixing an electronic cover of “I Want It That Way” sung in Mandarin; the next he’ll be recording a black metal band, or producing a twee pop single by a group from Spain. Oh, he’s also in an emo band, and yes he is aware what year it is. Rob brings a sincere and open-minded approach to each project he works on and will also talk about Godzilla movies if you want him to. But only if you want him to.
