Gamelan Gong Kebjar has been played on NTS shows including Fragrant Sacrifice w/ Naima Karlsson, 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.
