I recently came across this Mike Iverson youtube video about 5 percussive banjo techniques..I use some of these techniques but don't sound a good a he does, primarily because I haven't worked on them hard enough. None of the techniques are not all that difficult. I just impressed with how good something that is simple can sound in the hand of a good musician..
I've forwarded the video to several of my banjo students....Hope you enjoy this instructional video as much as I did.
