Watch the Add Expression online guitar lesson by Jon Herington from Ear IQ: Reactive Improvisation

Once you really know what notes you're after on each chord and you know where to find them on the fingerboard, you can start to experiment with expressive techniques like slides, bends, open strings, trills, hammer-ons, and pull-offs. You'll quickly hear how these techniques go a long way to bringing these chord tones to musical life.
