*Before hosting his May 10 concert in Baltimore in honor of Freddie Gray, Prince performed a similar tribute to Gray at his Paisley Park facility in Minneapolis on May 2.

Audio from that event, billed as Dance Rally 4 Peace, has been released, reports Billboard.

According to reports, attendees were also asked to wear the color gray.

“Thank you Minneapolis, we love you. Do me a favor and take care of each other, all right? It don’t matter the color. We are all family,” he told the crowd.
