A number of rock and metal musicians have voiced their support for the protesters in the wake of George Floyd demonstrations across the U.S.

The protests erupted after the Memorial Day killing of Floyd, an unarmed black man who died after a Minneapolis police officer pinned his neck to the ground with his knee for nearly nine minutes. In the weeks that followed, the “Black Lives Matter” movement has gone mainstream and has begun resonating with wider calls to address racism from Australia to Europe.

The “Black Lives Matter” movement was launched in the summer of 2013 by black organizers Alicia Garza, Patrisse Cullors and Opal Tometi after George Zimmerman was acquitted of the killing of Trayvon Martin. Following Floyd‘s death, the movement has gained even more attention. But some have tried to use a counterargument with the “All Lives Matter” label, which is seen as mocking the “Black Lives Matter” movement.
