East-West is the second album by The Butterfield Blues Band led by Paul Butterfield, originally released in 1966 on Elektra Records. It was recorded at the famed Chess Studios on 2120 South Michigan Avenue in Chicago. It peaked at #65 on the Billboard pop albums chart, and is regarded as highly influential by rock and blues music historians.

Even after his death, Paul Butterfield's music didn't receive the accolades that were so deserved. Outputting styles adopted from Howlin' Wolf and Muddy Waters among other blues greats, Butterfield became one of the first white singers to rekindle blues music through the course of the mid-'60s. His debut album, The Paul Butterfield Blues Band, saw him teaming up with guitarists Elvin Bishop and Mike Bloomfield, with Jerome Arnold on bass, Sam Lay on drums, and Mark Naftalin playing organ. The result was a wonderfully messy and boisterous display of American-styled blues, with intensity and pure passion derived from every bent note. In front of all these instruments is Butterfield's harmonica, beautifully dictating a mood and a genuine feel that is no longer existent, even in today's blues music.
