As always, Rory Block's teaching is clear and easy to follow. This Level 3 lesson is concerned with teaching riffs and slide techniques (in open G and open D tunings) that are used in the music of Robert Johnson. Of the three songs taught, only "If I Had Possession Over
Judgement Day" is taught at great length. The idea isn't so much to learn several songs by Robert Johnson, as it is to learn how Robert Johnson went about playing the guitar. The other two songs taught and performed are "Terraplane Blues" and "Preaching Blues". Rory also delves into how to approach the songs vocally. Well worth the money.
