Collections on County, Old Hat, Smithsonian have been mentioned, but also check out Yazoo, Document, Arhoolie and Old Homestead. The French label, Fremeaux et Associes, and the German Trikont label also had some interesting compilations. The major labels briefly released some fine albums such as Columbia's 'White Country Blues: A Whiter Shade of Blue' and RCA's Heritage Series, particularly 'Ragged But Right: Great Country Bands of the 1930s'. A great box set on Columbia that, like the Yazoo issues, interleaves recordings from black and white traditions is worth seeking out - it is available second-hand from Amazon at reasonable prices: Roots & Blues.
