You can build up expectations for a song before you record it, and then it's like nothing's good enough in the studio.
I have the barn, it's just kind of like a studio. Almost all artists have la studio to work in, and that's really what it is. A place to get away. I'll spend maybe four days out there if I can, just completely immersed - like where I don't bathe or brush my teeth for a few days, just get up and make coffee and experiment until the sun goes down.
