Experimental music opens up our ears. Should we become too rigid or inflexible in our thinking, sound can point us toward broader avenues and unexpected possibilities. This, says Michael Pisaro, is one way that experimental music reaches out into the world. But, he says, it doesn’t just reach out, it invites listeners in and asks them to interact with what they hear. Over the course of several emails, I talked with Michael about his sense of time in music, complexity in modern composition, why silence matters as musical material, and how sound is never exactly what it seems.
