Duo Nagai/Weitzel (since 2011)


with their broad influences ranging from contemporary composed music to noise music, free improvisation and music pedagogy, Chie Nagai and Joshua Weitzel create music that is thought from an idea of musical material found in experimental music but aims to maintain a playful, almost childish element.

現代三味線デュオ Contemporary Shamisen Duo (since 2014)

In this duo with Saito Ryota, we explore new possibilities in sound-making on the shamisen. Our research has given us a steadily growing repertoire of noises, emphasising extended technique and crossing the notion of "tradition". Our aim is to transport the shamisen into the 21 century chamber music context.
