Factory Sealed 1966 Heavy Vinyl Stereo Original. Pristine Copy. “The Second Butterfield Album Had An Even Greater Effect On Music History, Paving The Way For Experimentation That Is Still Being Explored Today. This Came In The Form Of An Extended Blues-Rock Solo (Some 13 Minutes) -- A Real Fusion Of Jazz And Blues Inspired By The Indian Raga. This Groundbreaking Instrumental Was The First Of Its Kind And Marks The Root From Which The Acid Rock Tradition Emerged.” Jeff Tamarkin, All Music Guide.
