The one and only Gladys Knight takes the stage for one night only at the Snoqualmie Casino Ballroom. What’s left to say about the Empress of Soul? With a singing career lasting over 60 years, very few artists could have the longevity of Gladys Knight. With countless awards, including four Grammys, Knight is considered a living legend in the genres of Pop, R&B and Gospel. Knight’s hits include “I Heard It Through the Grapevine,” “Midnight Train to Georgia” and “Love Overboard,” just to name a few.
