Guy Whatley performs a concert titled “The Maker of Organists” on the Paul Fritts organ at St. Alban’s. At the beginning of the 17th century, the Amsterdam organist Jan Pieterszoon Sweelinck trained a generation of organists who would radically change the trajectory of the instrument. Guy Whatley explores the music of the Amsterdam master, his pupils including Samuel Scheidt and Matthias Weckmann, and their influence on later generations.
