Back? I'm not sure it ever left, at least not in the circles I move in. I go to Clifftop every summer, and there are more people there evey year and they all seem to be very good banjo players! Of course in the general population, number of banjo players is still very small. If there is a banjo revival, I would give Dwight Diller an awful lot of the credit; he has been traveling around the country giving weekend banjo workshops which a number of my friends have attended and come away with a good appreciation for rhythm and timing. There's lots of different banjo styles and the one that seems to be most prominent is the old clawhammer style.
