The film uses Butterfield’s music and words, along with first-hand accounts of his family, his band mates and those closest to him. Butterfield, who died in 1987, is regarded by some as the greatest blues harmonica player of all time.
The film features appearances by David Sanborn, Bonnie Raitt, B.B. King, Elvin Bishop, Maria Muldaur, Paul Shaffer, Michael Bloomfield, Todd Rundgren and Bob Dylan. It has played at the Mill Valley, Woods Hole and Newport Beach Film Festivals.
The Paul Butterfield Blues Band was inducted into the Rock and Roll Hall of Fame in 2015. Butterfield is one of a handful of musicians inducted into both the Rock and Roll Hall of Fame and the Blues Hall of Fame, alongside B.B. King, Chuck Berry, Billie Holiday and Eric Clapton.
