Beyoncé just shared a behind-the-scenes video of a rehearsal for last night’s Grammy performance. In it, the star talks about why she chose a chorus of all black men. 

"I wanted to find real men that have lived, have struggled, cried and have a light and a spirit about them," said Beyoncé. "I felt like this is be an opportunity to show the strength and vulnerability in black men."

"My grandparents marched with Dr. King, and my father was part of the first generation of black men that attended an all-white school," Beyoncé adds. "My father has grown up with a lot of trauma from those experiences. I feel like now I can sing for his pain, I can sing for my grandparents’ pain. I can sing for some of the families that have lost their sons."
