60 Rockabilly Greats - The cradle of the mid 1950s rockabilly sound was, of course, the deep southern states like Tennessee, Mississippi and Texas but, in parallel with the Delta blues, rural Rockabilly migrated with its poor audience seeking a better life in the northern and western cities of the USA.It wasn't just black country folk who migrated north in the 40s & 50s, many rural white southerners left their homes too and, like their African-American counterparts, they wanted to hear the music from down home on the jukeboxes of the bars and honky-tonks of their newly-adopted hometowns.
