On January 10 1956, two months after leaving tiny Sun Records for RCA and two days after turning 21, Elvis Presley retired to a Nashville studio for his first sessions on the new label. The first song he cut was a cover of Ray Charles' "I Got a Woman," the second was "Heartbreak Hotel." The latter song, and Presley's follow-up hits, had such a commercially devastating impact on country music that for a time Nashville's famed 16th Avenue seemed to be the loneliest street in America.
