In 1970, Miles Davis was at the height of his powers, recording the Jack Johnson sessions. It was also a turning point for Davis: In this year he embarked on some of his most radical music, abandoning jazz and the expansive textures of Bitches Brew for a concentrated take on rock and funk that defies categorisation. Jack Johnson, released to little fanfare in 1971, marked that turning point.

Containing only two tracks, the album was assembled out of no less than four recording sessions between February and June in 1970, and was produced by Teo Macero. By any measure, Jack Johnson is a monster album.
