For those who aren't aware, this JACK JOHNSON soundtrack was compiled from 1970 studio sessions by Miles Davis for a rarely-seen documentary of the legendary boxer. The 2005 Ken Burns-directed UNFORGIVABLE BLACKNESS documentary with music by Wynton Marsalis is an entirely different audio/video project. Although Davis' music i.m.o. certainly evokes the spirit of Johnson, it also stands on its own musical merits as arguably one of the most outstanding Miles albums of his entire career (which is saying something because Miles' career is loaded with classic, timeless performances).
As I wrote of the boxed set of the JACK JOHNSON sessions, if ever progressive strains of jazz, rock, blues, and funk found common ground -- without selling any of the above short -- I'd argue it was in the early-1970 sessions from which this album was pasted together. JACK JOHNSON rocks steady, gets on the good foot, and does so with jazz intuition and blues feeling. Miles' playing is awesome, and I would consider his opening solo on "Right Off" to be as brilliant as any I've heard by him at ANY point in his career, finding a perfect, unpredictable balance between basic and abstract improvisational phrases. The rhythm section -- including John McLaughlin on guitar, Michael Henderson on electric bass, and Billy Cobham on drums -- throws down a steady beat that reacts to and pushes Miles onward and upward. Reedman Steve Grossman, keyboardist Herbie Hancock, more from Miles, and finally McLaughlin manage to keep this lengthy cut interesting, while some spliced-in segments from related sessions by producer Teo Macero keep the listener off-balance to good effect.
"Yesternow" builds slowly off of a Henderson bass motif, beginning quietly but eventually erupting into a electrifying riff that at one point has frequently uncredited guitarist Sonny Sharrock creating joyful noises that are apt to forever remain edgy as future generations discover this already 35-year old album. Those who are unfamiliar with JACK JOHNSON may have to make some adjustments to fully appreciate this album, given that it is comprised of two long tracks, spliced to their 20-plus minute lengths from various sessions (which btw are heard in unedited form on the excellent COMPLETE JACK JOHNSON SESSIONS boxed set). Also, there are no pre-written melodies as the music focuses mostly on solo statements by -- and the interaction of -- the musicians. If you can accept this album on its own terms, you're likely to be rewarded with an inspired listening experience no matter how often you play it. Which one can say of dozens of Miles Davis albums!
