Watch the Slippery Shuffle online guitar lesson by Jeff Scheetz from 50 Blues Rock Rhythms You MUST Know
In blues, doing the hammer on from the minor 3rd to the major 3rd is like a Rush concert attracting middle aged rockers - it's gonna happen! This is a pretty standard way of playing a 12 bar progression in a blues rock setting. You can do the hammer on/pull off trill separately to work it up to the speed you want. Keep this one grooving for maximum coolness!
