Rockabilly: Was this the purest style in rock?

A DEFT, HARD-DRIVING BLEND of country, gospel and blues, rockabilly was performed mainly by white artists who traded legitimate country backgrounds for a short-lived but frenzied involvement in music with a strong beat. Young, naturally exuberant musicians were the prime exponents, but traditional country singers were not without guile and, for a brief period around 1954-57, they too sang with a flash and glamour to match their rhinestoned clothes.
