In the 1960s, Simone was diagnosed with bipolar disorder. In 1964, Simone began to work with the Dutch record label Philips. She began to record songs about her African-American origins and racial inequality. She recorded a live album called "Nina Simone In Concert" which included the song "Mississippi Goddam". It was about the murder of Medgar Evers and the bombing of a church in Birmingham, Alabama that killed four black children. The song was boycotted in some southern states. With "Old Jim Crow" on the same album she reacts to the Jim Crow Laws.
