Chris Messina is a GRAMMY-nominated producer, mixer, engineer and songwriter, and one of Bon Iver's main creative partners.

They struck up a friendship when Chris was working on Bon Iver's world tour in support of his 2011 self-titled album. After that run Mr Bon Iver himself, Justin Vernon, asked Chris to quit working on the touring circuit and move to Wisconsin to manage his studio, as well as collaborate on creating music.

Chris did just that and played a key role in the making of Bon Iver's 22, A Million and i,i albums.

Before bunkering down with Bon Iver, though, Chris was touring the world working behind the scenes with artists like Madonna, Tom Jones and Lady Gaga, all of which we talk about in this interview.
