Two generations of arena R&B share one giant Houston weekend when Usher and Chris Brown bring The R&B Tour to Reliant Stadium. The production promises precision choreography, enormous singalong records, and a deep bench of slow jams, club hits, and pop crossovers from both headliners. With shows on consecutive nights, this is less a standard concert than a stadium-scale survey of modern R&B showmanship. Arrive early and expect the crowd to know nearly every chorus.
