Hey Fellas here is the backing track as requested, i think of this as a Blues- Soul Backing Track with a different turnaround which should make you think of your target notes differently.
The Chords are,
B Flat Minor
Turn around chords are C # Major - F minor - D# Minor- G#
Lots of possibilities here, Straight Pentatonic - Natural Minor or a hint of dorian at places.
THERE IS NO DRUMS SO IT IS A SUPER LOOSE GROOVE.
I hope you enjoy it and make sure to let me know if you get anything down over the top of it.
