It's amazing to me: when people start their career, you write about maybe a couple of topics, and you find that as you grow older, a lot of those topics never resolve, because I think your job as a writer is to pose questions as you see them. I don't know if we're supposed to give answers to people, because I don't know if we have any.
One day, I was just fingering around on the keys of a Fender Rhodes piano, and I came up with this little riff, and all of a sudden, it morphed into a song. It had never been touched by a guitar, which was very weird for us. 'Under the Ground' is the first song I have ever written that had nothing to do with the guitar.
