Simla is known in Thailand as one of the greatest living players of the khene, the ancient bamboo mouth organ particularly associated with Laos but found throughout East and Southeast Asia. His virtuosic and endlessly inventive renditions of traditional and popular songs have earned him the title ‘the god of khene’, and he is known for his innovative techniques and ability to mimic other instruments and non-musical sound, including, as a writer for the Bangkok Post describes, ‘the sound of a train journey, complete with traffic crossings and the call of barbecue chicken vendors’.

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).
