Organ music has been part of Christian worship services since the Middle Ages. It has a long history in concert programs, but in the early 20th century, the organ crossed over into public arenas and a new style of organ playing developed for silent movies, stage acts, and sporting events. WBFO’s Arts & Culture Desk producer Scott Sackett visited with organist Curtis Cook, whose innovative flair inspires audiences in the churches, theaters, and other venues where he plays.
