Try John Fahey. I haven't heard this particular Leo Kottke so I can't comment on the recording quality, but Fahey is the guy who started it all. Try to find some of his early recordings on the Takoma label to sample his genius. Kottke ain't bad but Fahey is in a league of his own.
Any others like L. Kottke Clone CD?
Wow. Just picked this CD up at the local Tower store and it is incredible. Are their other artists or recordings similiar to this with outstanding music and sonics?
