Campbell has 1 Geoffrey Gurrumul Yunupingu concert.

Geoffrey Gurrumul Yunupingu (22 January 1971 – 25 July 2017), 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 Gälpu, Gumatj or Djambarrpuynu, and in English.
