Rockabilly/Retro is a genre of music that emerged in the 1950s, fusing elements of country, rhythm and blues, and rock and roll. Characterized by its upbeat tempo, strong rhythms, and distinctive 'twangy' guitar sound, the genre is significant for its role in shaping rock music and influencing bands like The Beatles and The Rolling Stones. Key figures in the genre include pioneers like Elvis Presley, Carl Perkins, and Johnny Cash, whose influential works laid the groundwork for modern rockabilly artists. The genre's retro appeal has ensured its endurance, with a resurgence in popularity in the late 20th and early 21st centuries.
