I just came across this YouTube video Songs of Appalachia: Bluegrass royalty

Would someone please tell me what kind of style of banjo playing this is? And is this the same style of playing that is performed by the woman banjoist in this Carolina Chocolate Drops video?

Also, thanks JedMarum for posting links to videos. Does anyone else have any recommendations of which YouTube videos people should view that feature different styles of banjo playing?

Thanks in advance.
