BALTIMORE (AFP) - Reclusive superstar Prince refashioned himself on Sunday as a community healer as he led a peace concert in Baltimore.
Two weeks after sometimes violent protests erupted over the death of African-American Freddie Gray, who sustained injuries in Baltimore police custody, Prince threw what he called a Rally 4 Peace at a downtown arena in which he debuted live a song dedicated to the scarred city.
For the song, Baltimore, he brought to the stage Marilyn Mosby - the young prosecutor who pleasantly surprised many demonstrators by swiftly bringing charges against six police officers over Gray's death.
"Are we gonna see another bloody day? / We're tired of crying and people dying / Let's take all the guns away," Prince sang in Baltimore, released online before the concert.
The song, whose gentle guitar riffs reflect more hope than anger, also refers to Michael Brown, an African-American teenager whose shooting death by police sparked protests in Ferguson, Missouri.
"Does anyone hear us pray? / For Michael Brown or Freddie Gray? / Peace is more than the absence of war," Prince sings, before leading the chant, "If there ain't no justice, then there ain't no peace."
He drove home his message of empowerment in one of his signature songs, Purple Rain, as he told the crowd in an extended interlude, "The system is broken, so it's going to take the young people to fix it."
Prince, sprightly with elegant dance moves at nearly 57 years old, told the crowd to seek "peace" as much as "piece" - a slice of the economic output of their community.
"I want to stay tonight in a hotel that is owned by one of you," he told the crowd of thousands, many wearing gray at Prince's urging, in tribute to Gray.
The activism marks a revival of sorts for Prince. He foreshadowed the activism at February's Grammy Awards, where he used a brief appearance to back the Ferguson-inspired slogan, "Black lives matter".
Since his superstardom in the 1980s, Prince has made headlines not only for his music but for his idiosyncrasies such as changing his name to an unpronounceable symbol amid a dispute with his record label.
Even the tickets for the show - on sale three days in advance - showed a different approach for Prince who in recent years has grown fond of announcing concerts at the last minute.
But even if he has preferred the seclusion of his Paisley Park estate in Minnesota, Prince has never, from the start of his career, played it safe. In an allusion to his early risk-taking, he performed the title track of Controversy, his sexually and politically forthright 1981 album, with the opening lines: "I can't believe all the things the people say / Am I black or white? / Am I gay or straight?"
In a show of magnanimity not just political but musical, he performed for Baltimore Don't Stop 'Til You Get Enough by Michael Jackson - often described in the 1980s as his rival, even if the real extent of their hostility remains a matter of conjecture. The cover offered a chance for him to show off his ever-impressive falsetto.
He also demonstrated his voice's power on Nothing Compares 2 U, which was written by Prince but whose most famous interpreter - Sinead O'Connor - recently said she was finished singing it.
Yet his overall interest during the 2 1/2-hour show appeared not to be just to excite fans with his hits but to delve into the music's deeper roots - the blues, soul and funk, as driven by pairs of both trombones and saxophones. He set the measured tone of the concert with opener Let's Go Crazy - a song frenetic by definition, but which Prince performed with a restrained deliberation. He said proceeds from the concert would go to charity.
