Generally, Old time banjo is called, clawhammer, frailing, drop thumb or rapping. Bluegrass banjo is picked with three fingers Earl Scruggs style. There are many outstanding clawhammer players, Cathy Barton, Howie Burson, Kathy Fink, Sara Grey and Reid Martin, to name a few. I have a strong preference for clawhammer, and, wide open full speed bluegrass banjo sounds like a popsicle stick in a bicycle wheel (to quote an old friend whom I wont embarrass)
