The compilation is on JSP records, out of London.
Also look for "Cajun Country 2", another 4-CD box which is a companion to this one. C'est bon!

However, most all tracks, with a few exceptions, were lifted directly from commercial discs (eg. Sony's "Cajun Dance Party" and Arhoolie's Amede Ardoin disc, the Dennis McGee and Leo Soileau discs on Yazoo, etc.)

I'd hoped to finally get a clean copy of "Amede Two Step" without that tinny NR artifact present, but its the exact same recording as on the Amede CD. Same with Austin Ardoin Two Step. I was hoping to find an untruncated dub, but it has the same one... This isn't necessarily an issue, mind you, considering what all you get at that price!

I've seen a particular site that has both of these boxes, at $14 each. 8 CDs for $28? Not bad! I'd say GO FOR IT!

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.
