Prince kicks off his three-night run at Chicago’s United Center this evening. Making his three-show run at the arena a true residency, he will host Purple After Jam aftershows at Chicago’s House of Blues each night (September 23-26). While the full list of guests for each show has not been announced, Janelle Monae is a good bet since she will open for the Purple One at the United Center on September 26.
