I just got back from a terrific week teaching flatpicking guitar at Kaufman Camp in eastern Tennessee. Also teaching was one of my new favorite guitarists, Clive Carroll. Clive is one of the most exciting solo acoustic guitar players that I've seen, and equally skilled as a fingerpicker, flat picker, composer, and arranger. I left inspired, and ready to learn some of his techniques. Here's a great video from Clive with a few fingerpicking exercises to practice.
