I hereby recommend the music of Joseph Spence (died 1984). Bahamian singer/guitarist, often accompanied by the Pinder Family. Folk Music that defies description. Here's someone else's opinion:
He frequently employs counterpoint and rhythmic shifts so complex that they far surpass the musicianship of almost all non-classical guitarists working today, and his control of melodic variation is simply astounding. His voice, also inimitable, is used more as a secondary instrument than as a means for communicating words. It provides a solid, if somewhat gravelly, base for the guitar's fluid lines to play off of and frequently serves as a reminder of how the basic melody of a given piece goes, when the guitar variations have become almost too complex to follow."
Plus he named an album Happy All The Time, the greatest album name ever.
