This Gentleman plays some days on the corner of 16th Street and South Van Ness in San Francisco. He had no reply when I asked him his name. His instrument is the mandolin, played lap guitar style with a steel slide. The result is a psychedelic country western, with a preference for Hank Williams. It is good that the song titles are announced beforehand - it would be tough to recognize his covers otherwise.
My friend visiting from LA recorded a little bit on his iPHONE. Check the Vimeo link above, or better yet go and to listen a little while. I'll be damned if you don't feel somehow transported as you walk away.
