as "some of the most powerful and influential jazz-rock ever played." Critics in retrospective appraisals also note the uniqueness of Davis' playing and the crucial contributions of his band and producer on the album. AllMusic's Thom Jurek highlights its "funky, dirty rock & roll jazz" and "chilling, overall high-energy rockist stance". He also calls it "the purest electric jazz record ever made because of the feeling of spontaneity and freedom it evokes in the listener, for the stellar and inspiring solos by McLaughlin and Davis that blur all edges between the two musics, and for the tireless perfection of the studio assemblage by Miles and producer Macero". John Fordham from The Guardian observes a transition in Davis's playing from a "whispering electric sound to some of the most trenchantly responsive straight-horn improvising he ever put on disc". According to Fordham: Jack Johnson and Davis' other electric-period albums influenced rock musician Iggy Pop's early music with the Stooges. Around 1985, he purchased copies of Davis' Sketches of Spain (1960) and Jack Johnson in a no frills used record shop for less than $5. "They have been my inspiring companions ever since", he told The Quietus in 2010. "The one tears me apart and the other puts me back together." Track listing All songs were composed by Miles Davis.
