This project, Massif and Archipelago, is a field recording project initiated by Japanese sound artist Yasuhiro Morinaga, documenting traditional gong music by different Southeast Asian ethnic groups. The project aimed to examine the impact of the natural and social environment on the gong music culture of Southeast Asia. During the project, he visited over 50 different ethnic groups and made hundreds of recordings. This album presents a selection of the unique gong music from different ethnic minorities. The selected music has been divided into two broad sections: one focussing on the music from the Massif, i.e. mainland Southeast Asia (Central Highland of Vietnam and Northeast Cambodia), the other on music from the Archipelago, maritime Southeast Asia (the Luzon Islands of the Philippines, Borneo, Sulawesi, and the Flores Islands of Indonesia).
