Watch the Rock a Billy online guitar lesson by Joe Dalton from 50 Acoustic Blues Licks You MUST Know
This one has a rockabilly feel to it. I've used it in band situations, and also solo spots. I think it makes a great rhythm part behind a singer or soloist, but you can build a very cool bluesy solo piece using this as the basic groove. The first finger barre is the key to making this lick sound smooth.
