The Paul Butterfield Blues Band set the standards in the 1960s for kick-ass white electric blues. Arguably no other group could hold a candle to them.   In 1971 Elektra Records issued a two record set of The Butterfield Blues Band live at the L.A. Troubadour. The two LP set did not include the full concert. This CD, Live, Vol. 2, picks up the balance of the concert with eight rare tracks. Butterfield fans are going to want this disc to add to the first Live CD.
