Once in a rare while I become obsessed with a song. This week I have fallen into a sort of dreamy trance brought on by repeated listening to Grizzly Bear's Shift.  The layered voices and whistling even followed me into Ikea - one of the least romantic places on earth. I was wearing the song's atmosphere like a protective winter coat when I left the store and met this violet sky, then watched it darken as I drove home hitting the replay button.
