I am a huge fan of early blues/R&B/soul, and listen to it non-stop. Stax was distributed by Atlantic, but when Atlantic merged with WB, Stax got dropped. I don't care for much that Atlantic after that point. While Motown had some great albums/artists, I much prefer the early Stax recordings. While a slightly different genre, my preference has been and will always be Chess recordings. There are a lot of Chess record compilations out there, and should be included in any collection that contains English rock bands from the late 60s (Stones, LZ, Tull, etc.). A lot of similar artists can be found on Sun record compilations as well, and while overshadowed by Elvis/Cash/JL Lewis, Sun Records was the genesis for the Memphis R&B sensation.
