Formed in Chicago in the early 1960s, The Paul Butterfield Blues Band helped bridge the gap between traditional blues and the emerging sound of modern rock. Fronted by harmonica virtuoso Paul Butterfield and guitarist Mike Bloomfield, the group brought electric Chicago blues to a wider audience with their dynamic performances and groundbreaking debut album. Known for their raw energy, instrumental skill, and racial integration at a pivotal time, the band influenced generations of musicians and earned induction into the Rock and Roll Hall of Fame in 2015.
