“Born in Chicago :The Best of the Paul Butterfield Blues Band” (Varese Sarabande)-Chicago born harmonica ace Butterfield formed his highly influential and innovative urban blues outfit in 1964, joining forces with fellow blues enthusiast Elvin Bishop and, a little later, guitarist Mike Bloomfield to create a string of excellent albums for the Elektra label whose compelling power still remains intact some half a century later. This fine anthology brings together the best of the Butterfield band’s output from those far off days, including their archetypally hard driving re-vamps of Sonny Boy Williamson’s “Good Morning Little School Girl” and Howlin’ Wolf’s “Spoonful” and an extended version of jazzman Nat Adderley’s “Work Song,” which provided an impressive vehicle for some instrumental flights of fancy from Messrs Butterfield, Bishop and Bloomfield.
