The percussive new age soundtracks of '80s and early '90s Japanese TV, anime and manga built alternative worlds and pushed boundaries in the process. When Japanese composer Yas-Kaz left Tokyo for Bali in the mid 1970s he had little idea of how influential his trip would become. In studying the storied art of gamelan, the jazz and avant-garde percussionist opened a door to a world of sound and rhythm left behind by the West. The music he and his contemporaries made would become known as new age. It also happened to soundtrack the golden era of anime.
