The Mississippi River Flood of 1927 was the most destructive river flood in American history. In the spring of 1927, the river broke out of its earthen embankments in 145 places and inundated 27,000 square miles. Part of its legacy was the forced exodus of displaced sharecroppers, who left plantation life and migrated to Northern cities, adapting to an industrial society with its own set of challenges. Musically, the Great Migration fueled the evolution of acoustic blues to electric blues bands that thrived in cities like Memphis, Detroit and Chicago becoming the wellspring for R&B and rock as well as developing jazz styles. The Great Flood is a collaboration between filmmaker and multimedia artist Bill Morrison and guitarist and composer Bill Frisell inspired by the 1927 catastrophe. In the spring of 2011, as the Mississippi River was again flooding to levels not seen since 1927, Frisell, Morrison, and the band traveled together from New Orleans, through Vicksburg, Clarksdale, Memphis, Davenport, Iowa, St. Louis and on up to Chicago. For the film, Morrison scoured film archives, including the Fox Movietone Newsfilm Library and the National archives, for footage of the Mississippi River Flood. All film documenting this catastrophe was shot on volatile nitrate stock, and what footage remains is pock marked and partially deteriorated. The degraded filmstock figures prominently in Morrison's aesthetic with distorted images suggesting different planes of reality in the story-those lived, dreamt, or remembered. For the score, Frisell has drawn upon his wide musical palette informed by elements of American roots music, but refracted through his uniquely evocative approach that highlights essential qualities of his thematic focus. Playing guitar, Frisell is joined by Tony Scherr on bass, Kenny Wollesen on drums and Ron Miles on trumpet.
