eg:
Am7b5 - D7 - Gminor
You would play:
The A dorian b2 over the Am7b5
The D super locrian over the D7 (also known as the altered scale)
And then the G Melodic minor over the Gminor.
The D7 isn't usually just a D7, it will usually be altered in some way like a b9 or a #5 or something.
Songs that come to mind with minor 2-5-1s:
Autumn Leaves
Softly As In A Morning Sunrise
Miracle Blade 4: Gibs on touch.
