Mingus is Joni Mitchell’s 1979 collaboration with jazz titan Charles Mingus, who wrote several songs for the project. Mingus died shortly before the album was complete, and Mitchell dedicated it to him. Four songs by Mingus with lyrics written by Mitchell appeared on the album, including a version of “Goodbye Pork Pie Hat,” Mingus’ tribute to saxophonist Lester Young, and one of his most famous compositions.
