The Associated Press reports that blues and jazz guitarist Pete Cosey died May 30 in Chicago. He was 68.
His daughter, Mariama, says he passed away due to complications from an unspecified surgery.
Cosey was a busy session guitarist with Chess Records, playing on records by Etta James, Fontella Bass, Howlin' Wolf and Muddy Waters, including Electric Mud and After the Rain.
He is perhaps best known for his work as part of the Miles Davis Band between 1973 and 1975. He performed on four of Davis' most experimental works, Get Up with It, Dark Magus, Agharta and Pangaea.
By 1975, he had developed an advanced guitar approach — involving alternate tunings, guitars restrung in unusual patterns and a post-Hendrix palette of distortion, wah and guitar synth effects — that has influenced several guitarists, including Henry Kaiser and Vernon Reid.
Later in his career, Cosey returned to Davis' music as a member of Thee Children of Agharta, a group focused on performing Davis' electric repertoire.
