The Paul Butterfield Blues Band was a blues rock band formed in Chicago in the early 1960s. The band was named after its leader, harmonica player and vocalist Paul Butterfield.

Butterfield, who grew up in Chicago, was exposed to the blues at an early age and quickly became a proficient harmonica player. He formed the Butterfield Blues Band in 1963, and the group quickly gained a following in the Chicago blues scene.

The band's sound blended traditional blues with elements of rock and roll, creating a style that was influential in the development of blues rock. The lineup of the band changed over the years, but at its core, it included Butterfield on harmonica and vocals, Mike Bloomfield on guitar, Elvin Bishop on guitar, Mark Naftalin on keyboards, and Jerome Arnold on bass.

The Paul Butterfield Blues Band released several albums in the 1960s, including their self-titled debut in 1965, which featured the hit single "Born in Chicago." The band's later albums, such as "East-West" and "The Resurrection of Pigboy Crabshaw," continued to explore and expand on their blues rock sound.

The band's music was highly influential, and many later blues and rock musicians credit the Paul Butterfield Blues Band as an inspiration. The group was inducted into the Rock and Roll Hall of Fame in 2015. Despite the band's relatively short existence, they left a lasting legacy and are still regarded as one of the most important blues rock bands of all time.
