Two weeks after protests in Baltimore brought national attention to the death of Freddie Gray while he was in police custody, Prince came to town for a "Rally 4 Peace" ? a surprise concert that turned into an epic two-and-a-half-hour jam session with a dream set list and appearances by Doug E Fresh, Estelle, Miguel and State's Attorney Marilyn Mosby. After blasting off with favorites "Let's Go Crazy," "Take Me With U" and "Raspberry Beret," Prince launched into "Baltimore," a song about the city's struggles that he had released just over 24 hours earlier. Prince ended the show by telling the crowd, "The system is broken. It's going to take young people to fix it. We need new ideas, new life."??
