Not exactly a musician but someone who definitely influenced music bigtime:

Owsley 'Bear' Stanley dies in Australian car crash

A police statement said a man in his 70s died Saturday when a car he was driving left a highway and hit trees near the town of Mareeba in northern Queensland state.

Police would not confirm the driver's identity. But Oswald's family issued a statement to The Associated Press on Monday confirming his death in the car wreck. He was 76.

Stanley was a major producer of the hallucinogenic drug LSD in San Francisco in the mid-1960s. He also was an accomplished sound engineer who worked with the psychedelic rock band The Grateful Dead.
