Step-by-step explanation:
One early example of social protest through music is Bob Dylan. He was a 1960s-era musical artist who used his music to speak out against injustice and advocate for change. Dylan's songs like "The Times They Are a-Changin'" and his opposition to the Vietnam War made him a powerful voice for social change.
