This is my tribute to John Coltrane who would have been 93 on Sep 23, 2017.
In this improvisation over a Gmin7 pedal, I am utilizing several rhythmic and harmonic devices along with dodecaphonics. I am thinking a lot of the transition between Gm7 and Fm7/G which is essentially G Phrygian but I am also superimposing a lot of other harmonic material including chord progressions, inside/outside playing and at times just letting the melodic flow take me where I feel it wants to go.
I'm also using quite a bit of 3 over 4 and 5 over 5 rhythmic devices and some sheets of sound - out of time - playing.
I hope you find this useful.
