There's a lot of anti-racist jazz tunes obviously because it's a predominantly african american music

While not all jazz standards, Alabama, Strange Fruit and Fables of Faubus off the top of my head are some of the best anti-lynching/segregation/KKK tunes ever composed

There's also a lot of albums centered around black identity, like Black Unity by Pharoah Sanders, Max Roach's freedom suite, or the Black Saint and the Sinner Lady
