American Gamelan Institute for both new and traditional gamelan music, scholarly writings on gamelan, as well as audio and video recordings. Its founder and director is the composer and gamelan musician Jody Diamond. The organization's scope includes gamelan music as practiced in Indonesia as well as around the world.
