*Netflix is padding its original documentary slate with “What Happened, Miss Simone?,” a new film about iconic singer and civil rights activist Nina Simone.

Due in 2015, the doc from Oscar nominated filmmaker Liz Garbus, was made in cooperation with Simone’s estate and features more than 100 hours of never-before-heard audio tapes, recorded over the course of three decades. In them, Simone is telling her life story to various interviewers and would-be biographers. The film also includes rare concert footage and archival interviews, along with diaries, letters, interviews with Nina’s daughter, Lisa Simone Kelly, friends and collaborators, according to Deadline.

While Netflix has had success acquiring finished documentaries that have gone on to earn Oscar attention, “What Happened, Miss Simone?” marks the first time the streaming service joined a project at an early stage. Netflix is producing the Simone documentary with RadicalMedia.

“In ‘What Happened, Miss Simone?’, Liz Garbus paints a brave and provocative picture of Nina Simone – artist, civil rights activist and heroine – in a film that we’ve loved from day one and are proud to bring to our viewers around the world.” said Lisa Nishimura, Netflix VP of Original Documentary Programming.
