As anger spread through the music community, a message spread on social media calling on the industry to "take an urgent step of action to provoke accountability and change".

Among those reposting the message were Warner Music Group, Sony/ATV, Universal Music, Motown, Capitol Records, British label Dirty Hit, Eminem's Shady Records and legendary producer Quincy Jones.
"All of my shows are cancelled," wrote Apple's Ebro Darden on his Instagram feed. "I will air replays of conversations with community activists, politicians and revolutionary music."

Universal's chairman, Sir Lucian Grainge, also issued a memo to staff laying out plans for a task force, headed by chief counsel Jeff Harleston, to "accelerate our efforts in areas such as inclusion and social justice".
"We must do more and now is the time to do it - and to do it with an unprecedented sense of urgency," he wrote.
"Even more importantly, we must commit ourselves not merely for this week, but we must continue that commitment - without let-up - in the months and years ahead."
The British record industry's trade body, the BPI, also confirmed it would participate in the "Blackout Tuesday".
"Like many of our members, we will suspend normal business tomorrow," it said in a statement.
"Our staff will share in this moment to reflect on the recent tragic events, stand in solidarity with all those who suffer discrimination and encourage our leaders across the world to act.
