Prince announced on Tuesday he will give a surprise concert in Baltimore this Sunday in honor of the death of Freddie Gray.

A string of protests ignited last month after Gray, a 25-year-old black man, died of a severe and critical neck injury on April 19 after being apprehended by Baltimore police. According to officials, Gray was taken into custody for carrying a switchblade knife after being chased by police on the morning of April 12. However, an investigation determined there are no laws barring the knife he was carrying, which means his arrest was illegal.

Cellphone footage of Gray's arrest also revealed that Gray's legs appeared to be limp as he was being dragged into a police van. Witnesses at the scene also said that Gray was screaming in pain and his legs did not seem to be functioning properly.

Just days after recording a protest song inspired by the Baltimore protests, Prince announced that he will perform at a Mother's Day Rally 4 Peace concert at the Royal Farms Arena in Baltimore.

"In a spirit of healing, the event is meant to be a catalyst for pause and reflection following the outpouring of violence that has gripped Baltimore and areas throughout the US," according to a statement released by LiveNation, reports The Washington Post.

The pop icon is asking everyone to wear the color gray to honor Freddie Gray.

"As a symbolic message of our shared humanity and love for one another, attendees are invited to wear something gray in tribute to all those recently lost in the violence," the statement continued.

Prince will also debut his new single, "Baltimore," which "addresses the unrest in Baltimore and the socio-political issues around the country in the wake of a slew of killings of young black men," said Yvette Noel-Schure, a spokeswoman for the superstar, reports NBC News.

The lyrics from the song were recently made public. They read:

Does anybody hear us pray

4 Michael Brown or Freddie Gray?

Peace is more than the absence of war.

Live Nation added that "several industry superstars" are expected to appear at the show.

Tickets go on sale Wednesday at 5 p.m. while a "portion of the proceeds will be directed to the benefit of local Baltimore based youth charities," states the news release.
