Japanese percussion group, Spiral Arms is led by world percussionist Toshi Tsuchitori. The group mainly perform with the Japanese ancient drums called Kuretuzumi, which were originally only used in 6th~7th century Japan for the mask dance called Gigaku at that time. After this period, this drum completely disappeared from the Japanese music scene. Toshi Tsuchitori commissioned the reconstruction of these drums by a specialist Japanese drum maker, after which we formed the group, Spiral Arms to perform with these drums. The group consisted of Japanese and Korean-Japanese musicians.
