24 hours after announcing that he’d be attached to the project, Yasiin Bey (aka Mos Def) has confirmed that he will not appear in the upcoming Thelonious biopic, chronicling the life of jazzmaster Thelonious Monk.

In a four-minute video, the rapper/actor explains that he was unaware that the family of the late musician had condemned the project.

“Let me be clear, if the Monk estate is not happy with it, if Mr. Monk III is not happy with it, than neither am I,” he says in the clip. “To be clear I was given every indication by the production company that the family was on board, it was one of my primary questions… I took them at their word and clearly that was not the case.”

Indeed, upon the initial announcement of the movie, T.S. Monk, the son of the late, great musician said, “This project and its announcement are totally unauthorized! I hate the script and I control the music in Thelonious’ catalog. There is no involvement by anyone in the Monk family with this project, and we actually condemn the effort.”
