This morning’s show features three historical recordings, starting with Max Roach’s 1960 release of "We Insist: Freedom Now Suite" which made the most powerful artistic statement during the Civil Rights Movement. The second was a 1982 recording called "O Canto dos Escravos" (The Chant of the Slaves) that feature 14 selections of work songs sung in Portuguese and Bantu by Clementina de Jesus, Mestre Geraldo Filme Souza and Tia Doca. These songs were documented and transcribed by historian Aires da Mata Machado Filho when he visited São João da Chapada, Diamantina in the state of Minas Gerais. They were eventually published in a book entitled "O Negro e O Garimpo em Minas Gerais" (The Blackman and Prospecting in Minas Gerais) in 1943. And finally, Charles Mingus live concert at the Salle Wagram, Paris in 1964 with Eric Dolphy, Jaki Byard, Clifford Jordan and Dannie Richmond.
