Pattern Study licks like this are real useful lick in your vocabulary. I think I stole this off a piano player called Jim Watson of his piano trio album. It's a bit of pig in other positions but well worth the effort.
It works with the minor pentatonic and major pentatonic and once you get into it you will find it works in all kinds of situations. The live vid of "I don't need no doctor" solo I use this concept mixing maj and minor pentatonics which sounds pretty funky I think.
Do try it out in other Boxes (Patterns) because it is great for your mind to figure which fingering works best where and there are some places where it really just doesn't work, well for me anyhow.
