R&B star Miguel broke down onstage at the 2016 Wireless Festival in London on Friday (08Jul16) while referring to the recent spate of violence in the U.S.
The 30-year-old singer was left heartbroken by the tragic loss of African-Americans Alton Sterling and Philando Castile, who were both killed in separate police shootings this week (beg04Jul16), and the deaths of five cops, who were targetted by a sniper at a Black Lives Matter protest in Dallas, Texas on Thursday (07Jul16).
He told the audience during his set London's Finsbury Park, "There's a lot going on in the world right now and it's weighing heavy on my conscience."
Yelling to the crowd, Miguel insisted the acts of violence are meant to divide and separate people and instil fear, but the only way to affect change is to band together.
"I couldn't sleep last night," he said, as he began to fight back tears. "I will not rest. I can not rest. We can not rest any more! We gotta do something, we gotta say something. Sorry about preaching... but it's true. It's true."
The crowd cheered as he wiped his eyes, and he then led the crowd in chanting, "We're all that we got", before concluding his set with a message about spreading love, not hate.
"The truth is, the world is only getting smaller and somehow in these times, we're becoming more divided," he continued. "I don't understand how that happens. But while I'm on this... stage I'm thinking the best that we can do right in this... moment... is to show compassion and love and understanding."
"Beware of the seeds planted in the garden of your mind... fill it with love... We are the new majority, you hear what I'm saying?" he asked, before thanking the audience and leaving the stage.
Earlier on Friday, the singer posted a demo online of a song called How Many, which he had written in his London hotel room in response to the shootings.
The song opens with the lyrics, "I'm tired of human lives turned into hashtags and prayer hands/I'm tired of watching murderers get off."
Miguel wasn't the only one to reference the shootings at the Wireless Festival - The 1975's frontman Matt Healy wore a U.S. flag around his waist and, when introducing one track, he said, "This song's about loving people as opposed to... shooting them."
Scottish DJ Calvin Harris headlined the show, bringing out specials guests including rappers Dizzee Rascal and Big Sean. Jaden Smith, son of Hollywood stars Will and Jada, was spotted celebrating his 18th birthday in the VIP section of the crowd with his sister Willow.
