The Dropped D tuning is very useful. You can easily play in the keys of D, G and A. It offers advantages in each of these keys. For a blues in A it is especially cool as when you play the fourth chord, the D7, you will have a low, booming D note on the sixth string. I picked up this idea from Mance Lipscomb.
"County Line" is an original instrumental based on Mance's playing of "Shake, Shake Mama". Mance would general use a monotonic bass approach. Instead I am employing an alternating bass throughout the arrangement. The opening phrase is very melodic and drives the playing.
