I sat down to learn "Keep Your Dress Tail Down", and realized how much it has in common with Pine Grove Blues.

Both used that pull blues scale, however, "Dress Tail" does not run out of air like Pine Grove does.

I was confused by the bluesy sound at first, thinking he was on a multi-row, but the tuning sounded like a single row.

I'm only on the intro so far. Just sharing my surprise, as the two sound fairly different in their treatment.
