One big difference between folk and pop musicianship has always been that folk performers don't seek applause for flash. They have no "future gigs" or record contracts in mind and don't care much about impressing people with "what they can do." When great folk performers like Jeannie Robertson or Frank Proffitt or Mississippi John showed their virtuosity, it wasn't the pop kind ("Hey! Look what I'm doign now!") that the commercial audience expected. They just did their thing with virtuoso sensitivity to the music and to the past and hoped we liked it.
