Big Bill Broonzy (1893–1958) was a highly influential American blues musician, known for his rich vocals, masterful guitar playing, and ability to blend Delta blues with urban Chicago styles. A prolific songwriter and performer, Broonzy's music touched on themes of love, hardship, and social justice, making him a key figure in blues history and a bridge between traditional acoustic blues and the electrified Chicago sound. His songs like "Key to the Highway" and "All By Myself" continue to inspire musicians worldwide.
