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.

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.

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 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.

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

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.
