In September 1900, Carl Stumpf (1848–1936) recorded this performance of a theatre group from Bangkok in Berlin on a phonograph cylinder which is still preserved in the Phonogramm-Archiv Berlin. In 1963, the Phonogramm-Archiv, which was founded in 1904, has become part of the Department of Ethnomusicology of the Ethnological Museum which belongs to the National Museums in Berlin – Stiftung Preußischer Kulturbesitz.
