I should also state that, in any case, they have some exhaustive (but, as always, very nice on the budget) comps of old-timey music if that's your thing. The complete recordings of Charlie Patton, near complete (may be complete, I didn't check) recordings of Uncle Dave Macon, and various others.
They even have a Paramount Records box set, which I believe contains some previously uncomped cajun stuff as well.

Their website isn't totally functional, and instead of text its all image oriented, and you'll have to do a lot of left-to-right scrolling to read the releases pages.
