Ryoko Ono is a Japanese saxophonist, flutist, composer, and recording artist specializing in improvised music and works for saxophone and electronics. She plays in a wide range of genres, not only improvised music, but also blues, jazz, progressive rock, noise, and avant-garde music. For acoustic sax solos, she uses circular breathing and multi-phonics to endlessly explore and pursue rich and complex sounds. Additionally she employs electronics for live performance using her own midi system controlled by a foot trigger to alter the sound of her saxophone with various electronic sounds and effects.
