Watch the SECTION 2: Performance Studies online guitar lesson by Adam Miller from Acoustic Groove
The Performance Studies take the Concepts and put them into practice. I've taken five contrasting and common grooves - mainly simplified versions of my own compositions. The studies will not only challenge your rhythmic technique, but also expand your chord knowledge and comping ability. Some of these studies are in non-guitar friendly keys too, which I think is an an important thing to learn to do without a capo!
