Man, this is gonna expensive. Just read the artist bios on the page and now want to listen to any single one of those.
In case you don't have it, I warmly recommend Cedric Burnside's record. I got one copy from a VMP clearance sale and it's really good. Thanks you @Reed for offering free shipping even for internationals buyers. I already have both Atkins and Burnside's records but will give a listen to these suggestions.
