I know I tend to bleat on about him in many of my posts but I cant overstate how awesome Leo Kottke is and Ive heard thousands of guitarists in my time. 'My Feet are Smiling' is one of his live recordings and it's the kind of stuff that has you picking your jaw off the floor. Before he did his hand in from having such a meaty style of fingerpicking he used to play with steel finger and thumb picks on both 6 and 12 string! The ultimate acoustic shredder, in my humble opinion he's the best guitar player ever to come out of the US.
