I want to know the answer to the following question:
What Tennessee recording company first promoted Elvis Presley?
All the background I'm provided with is that "Memphis is also home to Sun Records, where musicians such as Elvis Presley, Johnny Cash, Carl Perkins, Jerry Lee Lewis, Roy Orbison, and Charlie Rich began their recording careers, and where rock and roll took shape in the 1950s.[not verified in body]". Is that enough to answer the question?
