Watch the Our Man in Toronto online guitar lesson by David Hamburger from 50 Jazz-Blues Licks You MUST Know
This ii-V lick makes use of a similar device as the previous one: you make your way through the ii chord with a combination of spot-on (minor seventh) chord and (Dorian) scale tones, but then, as the V chord hits, instead of playing dominant seventh chord tones and/or Mixolydian scale tones over the V chord, you just kind of slide into the beginnings of a bluesy I-chord lick and continue on with same as the I chord arrives. It’s very slinky and cool, and keeps you from sounding like you’re running through your excercises from the Materials and Principles of Jazz Improvisation class (and I should know - I took those classes and practiced those excercises myself as an earnest but very average undergraduate jazz student). I suppose it works because the V chord and the I chord are both built out of notes from the same scale, but at the end of the day it mostly works because this is apparently what guys like Joe Pass and Oscar Peterson like to do and it sounds freaking awesome when they do it. I love it because it’s the kind of idea you can grab and start messing with yourself right away. All you have to do is think: "okay - play ii stuff over the ii, then play bluesy I stuff over the V and the I." Done.
