The music world is mourning the loss of musician and producer Jim Dickinson, who died Saturday (Aug. 15) at a Memphis hospital after undergoing heart surgery earlier this year. He was 67. He is perhaps best known for his work as a session musician, having played piano on the Rolling Stones' 1969 recording of "Wild Horses" and Bob Dylan's 1997 album, Time Out of Mind. His production work included projects with the Replacements, Big Star, Ry Cooder and, more recently, singer-songwriter Amy LaVere. In addition to his recordings with the Atlantic Records house band, the Dixie Flyers, Dickinson also recorded a series of solo albums, including Dinosaurs Run in Circles, released earlier this year. His sons, Cody and Luther Dickinson, are members of the roots music band, the North Mississippi Allstars.
