In the wake of Philando Castile and Alton Sterling’s deaths, Solange has shared an a cappella cover of Syreeta’s “Black Maybe.” Both men were fatally shot by police this week.

“Been singing Syreeta’s ‘Black Maybe’ over and over again trying to comfort my weary heart,” she wrote on Instagram alongside a video of her cover. “But what is comfort when the images of slain black bodies left to bleed are sketched into your being…over and over again. #AltonSterling #PhilandoCastile

Solange also posted a screenshot of the 1972 song’s lyrics, which were penned by Stevie Wonder for Syreeta’s self-titled debut. “Black maybe it’s time for you to wake up, come around, come around,” they read.

Earlier on Thursday, the youngest Knowles took to her sparsely populated Twitter in response to the deaths. “I can count 5 parents in the last 3 hours who have text me and said my child just asked me ‘AM I GOING TO DIE’?!?” she tweeted. “The TRAUMA that is being passed on to us, and OUR CHILDREN by this non stop murder of our brothers and sisters is sickening…”

Over the years, Solange has been active in the ongoing discussion surrounding police brutality in America. In 2013, she led a peaceful protest for Trayvon Martin in Brooklyn, carrying a sign emblazoned with a quote from Malcolm X: “I’m for truth, no matter who tells it. I’m for justice, no matter who it’s for or against.”

The 30-year-old singer joins a slew of celebrities that have condemned the shootings, including Chance the Rapper, John Legend, Taraji P. Henson, Drake, and Blood Orange’s Dev Hynes. “Don’t forget to set your clocks back 300 years tonight,” reads an image shared by Questlove. “I Want Your Name To Be Your Name #IDontWantToHashTagAnotherName.”
