"All Blues" (Miles Davis)

Along with the iconic “So What,” the track “All Blues” also is a cornerstone of the jazz classic, Kind of Blue (1959).  Much like “So What,” there was little or no practice before the musicians recorded "All Blues."  Miles Davis told them the basic structure and the chord changes he had in mind, and away they went.  
It’s Take #2 that you hear on the album.
The song gets its name from its core musical structure: the 12-bar blues.  That said, Davis doesn’t exactly have his musicians play the game straight.  Instead of sticking to a traditional I chord/IV chord/V chord blues progression, they move around the scale a bit, dipping to minor chords and chromatic chords outside the scale along the way, creating alternating waves of electrifying dissonance and mellow resolve every few measures.
Also, Davis utilizes waltz-like 6/4 time instead of common 4/4 time, giving the song a special, lilting swing that the musicians ride for well over 11 minutes.  
Although, it doesn’t feel like 11 minutes.
In fact, it’s not uncommon for me to hit “repeat” three or four times on this track.
