Johnny Cash With His Hot and Blue Guitar ! (1957)

They used to call me Rockabilly

all of us ran through

When Elvis opened up the door 

with a pup-and-pup-and-boo
I didn't ever play much rock and roll 

cause I got so much country in my soul

 Johnny Cash

This will ease us out of Rockabilly mode for a while. As Johnny himself said, he was never anything other than Country, but the Country and Rockabilly sounds got pretty close in Memphis back then.  

This was the first ever LP on Sun Records, and a lot of the characteristics of the early Rockabilly sound are strongly in evidence.
