Finally - BOTH collections are great. It's the great bulk of everything Clifton recorded in the 50's which includes all the material he recorded for L.A.'s Specialty label which yielded his first national hits (so the Specialty release overlaps 100% with these). So great, raw, rockin' stuff! And if you have not explored zydeco, one of the nicely exotic yet oh so familiar strains of indigenous exotic (at least to mine Polish descended sensibilities), and you wanna start from square one - this is basically it.
Ergo the point is - DON'T BUY BOTH! But either one is essential!
