Like the 2-5-1 in major this is quite a reoccurring progression in many different styles. Its originates from the Harmonic Minor scale and the chords are IIm7(b5)-V7(b9)-Im(maj7). In the video I show you a scale (that really has no name) that fits these 3 chords, and if learned in all keys, will cover your basic soloing needs for this kind of progression. It is basically a natural minor scale with an added major 7th. To me it sounds a bit like a bebop scale so it naturally sounds its best when played in a descending fashion. This is the scale in Cminor:
C D Eb F G Ab Bb B (C)
