Tuvan throat singer Kongar-Ol Ondar has died after emergency surgery to treat a brain haemorrhage. He was 51. The musician passed away at a hospital in Kyzyl, the capital of Tuva, on Thursday (25Jul13). Ondar first came to prominence to Western audiences in the early 1990s and is largely credited with popularising the singing style, which involves simultaneously vocalising one or more notes over a fundamental pitch, of his homeland to global audiences. He also featured in the 1999 documentary film Genghis Blues, about a blind California blues musician who travelled to Tuva to learn about throat singing. Ondar's longtime friend Sean Quirk has paid tribute to the star, telling Reuters, "He is not replaceable. There's so much of Tuvan culture that's concentrated in him and who he was. He was the ambassador of Tuva."
