(Jazz Alley) Leo Kottke is a phenomenally fluent acoustic guitarist, a more antic John Fahey, you could say, with the bonus of being a hilarious raconteur between songs. Now 67, Kottke can play in folk, jazz, rock, and blues idioms with flamboyant virtuosity. His 1969 LP 6- and 12-String Guitar remains one of the most impressive displays of mercurial playing of those instruments in the history of recordings. Not sure if he's still as fleet of finger these days, but his large, great catalog and eccentric sense of humor should make you err on the side of attending.
