Geoffrey Gurrumul Yunupingu (22 January 1971 – 25 July 2017), commonly known as Gurrumul and also referred to since his death as Dr G. Yunupingu, was an Indigenous Australian musician. A multi-instrumentalist, he played drums, keyboards, guitar (a right-hand-strung guitar played left-handed) and didgeridoo, but it was the clarity of his singing voice that attracted rave reviews. He sang stories of his land both in Yolŋu languages such as Gaalpu, Gumatj or Djambarrpuynu, a dialect related to Gumatj, and in English. Although his solo career brought him wider acclaim, he was also formerly a member of Yothu Yindi and later of Saltwater Band. He was the most commercially successful Aboriginal Australian musician at the time of his death. As of 2020, it is estimated that Yunupingu has sold half a million records globally.
