Big Bill Broonzy was an American blues guitarist and songwriter who began his career in the 1920s playing country blues for African American audiences. By the 1930s and 1940s, he had transitioned to a more urban blues style and was a precursor to artists like Muddy Waters and Willie Dixon. In the 1950s, Broonzy returned to a more traditional folk-blues style and became a leading figure in the emerging American Folk Music Revival. He is considered one of the most significant blues figures of the 20th century and was inducted into the Blues Hall of Fame in 1980. Broonzy was a notable acoustic guitarist and inspired artists like Muddy Waters and Memphis Slim. He recorded over 350 songs during his lifetime including Key to the Highway which was famously covered by Derek and the Dominos.
