2017 collection. The Paul Butterfield Blues Band was one of the most important American bands of the ’60s, featuring Paul Butterfield (harmonica/lead vocalist), Mike Bloomfield, and Elvin Bishop. Unlike the British blues revivalists, the Butterfield band was schooled in the tough Chicago bars that housed Muddy Waters, Little Walter, and Howlin’ Wolf. They didn’t imitate the blues, they were the blues. Songs featured are “Work Song,” “Drowned in My Own Tears” and “Born In Chicago.”
