I like working with sound—sound and rhythm. I like the abstract more than “What does that mean?” Nobody ever says to you, “Why did you use a harmonium?” Or “What is that ringing sound that occurs here?” The questions are always “What does that song mean?” or “What were you trying to say here?” The abstract is just more interesting because it doesn’t really have anything to say, but if it is good, it creates thoughts and feelings, and I enjoy that. For me, once the music creates those thoughts and feelings, I begin to write a song about it. But if I just left it at the instrumental track, I think people would listen to it and think up their own songs and thoughts. That would be fun, too.
