Kenichi Iwasa and Naima Nefertari form the duo Exotic Sin. Improvisation and live recording are at the core of their collaborative process, integrating playful contrasts and cohesions of natural, digital and electroacoustic sounds. The duo collide piano, trumpet, flutes, percussion and two of Don Cherry's "zen saxophones" (woodwinds handmade by attaching reed mouthpieces to plastic plumbing parts), with loops, live sampling, and anachronistic '90s keyboards. The duo first came together in 2018 for a performance celebrating the art and music of Naima's grandparents, Moki and Don Cherry, before continuing as an independent unit that still incorporates some of the Cherrys' instruments as well as their synergetic integration of improvised music with visual art.
