Gamelan Gong Kebjar has been played on NTS shows including Fragrant Sacrifice w/ Naima Nefertari , with Kebjar Hudjan Mas first played on 17 December 2019.

Gong Kebyar (or Gong Kebjar in the old orthography, pronounced the same) is not an artist at all, but a genre of gamelan music from Indonesia.

If tracks have this listed as the artist, that's an error from some metadata getting mixed up.
