What an exciting enterprise! Beam me UP, Scottie!! When I think of albums I like, a lot of the above advice, good tho it is, goes out the window. You might think about sticking with the stuff you like the best, feel the most comfortable with, the stuff you roll out when nervous or unsure, certain it wont fail you. Do stuff that you have made your own, over years of playing...doesn't matter if it's been done B4, so long as it's your own rendition. I'm very partial to Delta blues myself, but what gets me going is aniything that is sung with conviction and passion, that isn't predictable or tired. I know you've got a million of 'em!
If you're the real thing, then doing what you love will surely be in the groove. And I agree w/Art...full up that sucker! The bird is on the wing...put as much out there as you can...you wont run out!
