Cause of death: cancer
Ali Ibrahim "Ali Farka" Touré (31 October 1939 – 6 March 2006) was a Malian singer and multi-instrumentalist, and one of the African continent's most internationally renowned musicians. His music blends traditional Malian music and its derivative, African American blues and is considered a pioneer of African desert blues. Touré was ranked number 76 on Rolling Stone's list of "The 100 Greatest Guitarists of All Time" and number 37 on Spin magazine's "100 Greatest Guitarists of All Time".
Some years after his death, a group of musicians playing in his style performed as the Ali Farka Touré Allstars (2012), and later the Ali Farka Touré Band (formed 2014).
