Unlike that guy in "Deliverance", Mark Kroos doesn't need a kid from the back woods of West Virginia to play Dueling Banjos. Mark plays both parts by himself. 

In order to do this Mark fret taps on a double necked guitar. As always some will be upset that there isn't a banjo played at all, but its still impressive. The hard work and concentration that goes into playing this must be insane. Good Job Mark.
