For a long time in the 1970s, I was experimenting to build musical instruments and use them. I did a lot of ethnic music studies and other things, like electronic music. Making homemade musical instruments and performing was my major activity from the time.

I don't think I differentiate between composition and improvisation. Improvisation could be a large part of a composition.

At the beginning, I felt sort of reluctant about my music from my past. But in the last couple of years, I felt good about what I did in the past. The way I see my work, time passes from the time I performed or recorded a work. When I look at it now, 25 years or 30 years ago, if I see that it has value today, I will agree to release it.

When I was just getting started making my own music, my dad said, "You should think about art, but also anti-art and non-art."

I don't want to release things too similar to each other. I've been working on selecting something different from my other work.

I wasn't so interested in merchandising through CD or whatever form. I wasn't really so aggressive about promoting my own work. I had my recordings from the past, but I never thought someone was interested in releasing it.
