Ricky Gardiner, a Scottish guitarist best known for his work on classic records by David Bowie and Iggy Pop in the late 1970s, has died from Parkinson’s Disease. Bowie producer Tony Visconti shared the news in a Facebook post today, having learned of it via Gardiner’s wife Virginia. “Another guitar genius and personal friend passed into the next world last night,” Visconti wrote. In a separate post on Twitter, Iggy Pop wrote, “Dearest Ricky, lovely, lovely man, shirtless in your coveralls, nicest guy who ever played guitar. Thanks for the memories and the songs, rest eternal in peace.” Gardiner was 73.
