James Blake spoke to Pitchfork
about working with the Bon Iver musician: "I explored sitting at the piano and singing a lot more. I would talk with Justin Vernon, who is a great producer—a lot of people may not know that about him. He's a good person to talk to. Much like Rick [Rubin], actually. Justin is an incredibly warm man. We've become really good friends.
When I first met him, it felt like we had been separated somewhere down the line and were meeting each other again. It was a very strange feeling. In the studio, he would say things like, 'Oh man, I love the chords in that track,' and that gave me so much confidence. Singing standing up at a mic with someone else recording was new, too; there never was any time to set up properly before."
