When you see Dionne Warwick perform, you know you’re in the presence of pop-music royalty. This is a woman who’s remained one of America’s top hitmakers throughout multiple eras, contributing classic songs one after another. At the same time, Warwick radiates the warmth that lies at the core of her legendary hits, and for all of her undeniable elegance, her onstage presence couldn’t be more natural and down-to-earth. Despite the many decades Warwick has been bringing her unique brand of pop to the stage and studio, her sultry, hypnotic voice remains undiminished. Hearing her deliver songs she made famous, like “I Say a Little Prayer” and “What the World Needs Now Is Love,” is like opening a love letter from another era that bears just as much of an emotional impact today as it did back then.
