Scottish bagpipe has two tenors and one bass - three drone pipes - and then the one chanter. If you put bagpipes together, it creates such a fine sound.

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.

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 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.

I remember, in elementary school, being asked what my father does and not knowing how to answer. When I asked my mom what I should say next time, she replied, "Just say he's self-employed." I love that.

I would sing myself with a tambura and just regular a cappella singing and practicing. I did that around 1973 and 1974, and I finally developed my own style of singing.
