Writing a song is a long road. Or it can be.

It's hard to imagine the whole punk movement without The Velvet Underground. I toured with them when they did their reunion tour, and no one sounds like that; they are a very unique-sounding band. They have a lot of noise, they have a viola, they have a drummer that's standing up, certainly they have influenced my guitar playing, but hopefully after 12 records you start to sound like yourself.

If I look at my own recordings, I think generally there is a focal point within the song and often it's the instrumental bridge or a guitar solo where we try to do something unexpected, something beautiful or weird, or beautiful because it is weird. And of course I fail half the time, but yes that is the goal, to create even a few seconds of bliss, or sadness. The electric guitar is a great instrument for doing this because it is capable of surprising you. There are so many different sounds available.

It's a scary question for a musician or songwriter today - what does the future hold? It is a strange time in the music business too; it feels like we are all in some kind of transitional period, stuck between old technology and new.

They didn't teach Nietzsche in the philosophy department at Harvard; philosophy there was strictly analytical stuff and the poetic ramblings of Nietzsche did not belong. And see - you are teaching it in a literature class - so they must have been right.

Writing songs does not get any easier, and that might be because I am harder on myself than I was twenty years ago. Hopefully, as we grow older and change, there are fresh topics, new perspectives, or at least there should be.

It's not often I get to do a film that turns out good. Plus, there just aren't that many great directors out there. There are a thousand different decisions that need to be made with each script and it's the good directors that can make those decisions. It's a long and complicated process in regards to what looks good on paper. Working on a bad film can be fun too. It can be a good exercise that gets you writing.
