Barbara McCullough‘s newest film, Horace Tapscott: Musical Griot, is a profound meditation on the importance of the black tradition to the music, art, history, and activism of Los Angeles and beyond. Horace Tapscott was an underappreciated musical genius and community activist deeply involved in one the most exciting periods of Los Angeles jazz history. Black-listed in the 1960s and ‘70s because of his political affiliations (his “Arkestra” was the band of choice to perform at political rallies), during the Watts Rebellion of 1965, police actually shut down his performances, accusing him of inciting people to riot with his music. Horace Tapscott: Musical Griot tells his story in the manner of a griot, or story-teller, who in West African societies maintain the legacy, knowledge, and history of their group traditions in oral form.
