Those recordings of Gongs Orchestras were made during Funeral Ceremonies in two Krung villages and one Jaraï village in Ratanakiri province, Cambodia by Laurent Jeanneau (Kink Gong) in 2003 and 2004, at a times when jungle had not been replaced by rubber plantations. Focusing on funeral's ceremonies, those hypnotics pieces are intense and haunting harmonics sonic experiments. "Adventure brought me to south-east Asia, not academic research. I was based on and off in Banlung, capital of Ratanakiri province between 2003 and 2006. Finding gongs orchestras became my obsession, I've witnessed different contexts in which gongs were being performed, but the most brainwashing ceremonies were the funerals, because they would never end, I remember leaving the 3 days funeral ceremony of a prominent Jaraï dead man in Tang ji village at the border with Vietnam and still hearing the gongs the entire next day going back home through the jungle". Laurent Jeanneau (Kink Gong) "Many of the ethnic minority groups, the Jarai, Kac_, Tampuan, Kavet, Kreung, Brao, Bunong, Mnong, Edé, and others, are hill-rice farmers who live in the uplands of the Annamite mountain chain. Collectively these groups have been known by many names, including a number of disparaging terms in local dialects, such as moï, kha, phnong, and others. The term Montagnard was applied to them by the French during the colonial period, and was used by the US military and in popular discourse in English during the United States-Vietnam War. In scholarly and popular literature during the mid-twentieth century these upland farmers were also called hill tribes. I have opted for the word highlanders as a relatively neutral term that avoids the semantic burdens associated with these other namings."
