Murphy Henry teaches the lower break of Earl Scruggs's signature tune, "Foggy Mountain Breakdown." This is from the Murphy Method DVD "Beginning Banjo Volume 1", which is available in its entirety here.
Regarding video quality, please keep in mind that this was filmed on video tape in about 1988 or so! The audio quality is great, but it's in standard definition (not HD).
