'This song and this film are a middle finger to the silence that ‘polite society’ has asked of people in pain,' says Morello.

The benefit livestream also featured Dropkick Murphys, The Interrupters, Josh Klinghoffer and more.

Morello explained the 'F--k you I won't do what you tell me' lyric too.

He also directs the video for the previously unreleased song.

'Racism in this country is as American as apple pie and baseball,' says Morello.

The diverse collective are rallying to unify people of all races in the fight against racism.
