There is a whole new breed of guitar players out there who are using innovative techniques to get sounds out of their instruments that would make Jimi Hendricks envious, so I thought I'd give a few of my favorites a plug:
Don Ross and Andy McKee
Antoine Dufour wth Tommy Gautier,
Dufour and Gauthier getting a wee bit silly with an old Jerry Reed tune,
and possibly the best of the bunch, Erik Mongrain, here and here.
They were all apparently influenced by a guy named Michael Hedges, who was experimenting with tapping/slapping techniques and harmonics back in the late 80's, and is absolutely mesmerizing to listen to.
