Unforgivable Blackness, which will be broadcast on PBS in January 2005, tells the story of boxer Jack Johnson, the first African American heavyweight champion of the world. Marsalis also collaborated with Burns on his 2000 PBS series Jazz, serving as senior creative consultant and appearing as an on-screen commentator.
Jazz at Lincoln Center hosted a Jack Johnson Festival earlier this month, presenting clips from Burns's film and music from Marsalis's score.
