Big Time Grain Company featuring David Williamson and Katie Heizer

David Williamson brings depth, soul, and seasoned musicianship to every performance. Born in northern Virginia and raised in the Shenandoah Valley, David’s musical journey started early—playing piano at age eight, then picking up guitar, drums, and bass as the years went on. His versatility and ear for melody have made him a sought-after performer, blending country roots with emotional authenticity. Influenced by artists like Cody Johnson, Luke Combs, and George Strait, David channels that same raw honesty and timeless sound. As General Manager of Guitars and Cadillacs, he’s a respected leader in the Kansas City music scene and brings that professionalism and passion to every show. Katie Heizer grew up in a home filled with harmony—literally. Surrounded by instruments and voices from an early age, she found her foundation in music through years of leading worship in church, where she developed a deep connection to the emotional and communal power of song.
