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’.
