• 1955 was one of the most prolific years for new artists, many of whom would revolutionize country music. Some of the more prominent names were Johnny Cash, George Jones, Elvis Presley and Porter Wagoner; it was also the year one of the best-known duos ever — the Louvin Brothers (Charlie and Ira) — would join the Grand Ole Opry. Many of them would go on to record and popularize the best known songs in the genre, and have recording careers that lasted for decades. It would be more than 30 years before another gifted group this prominent would rise to fame and create a revolution in country music in a single year.
