The Minnesota-born rock superstar wants you to wear gray to his Baltimore concert.

Amid all of the police brutality and economic disparity in blighted areas of Baltimore, Prince will play a Rally 4 Peace concert in the area. As symbolic message to help remember those who were lost, Prince and others have asked those who show up to wear something gray in a show of solidarity. He’ll be joined onstage by funk-rock group 3rdEyeGirl.

The multi-talented musician wrote a song about the late 25-year-old Freddie Gray, the man at the center of the Baltimore debacle, when the pot boiled over with protests and riots  earlier this month; he made the lyrics available to the public, which echo the sentiment of reconciliation and rehabilitation, but the song itself has yet to reach anyone’s ears.

Tickets for this very special show are on sale now. A portion of the proceeds will go to local Baltimore based youth charities. Grab your tickets right here.
