On the Mighty Flentrop Organ | Saint Mark's, Seattle 

Canon for Cathedral Music Michael Kleinschmidt offers a short introduction to the five divisions of the landmark pipe organ of Saint Mark's Episcopal Cathedral, Seattle, originally manufactured by the Dutch firm Flentrop in 1965. This video is rather longer than all the others in the "On Saint Mark's Cathedral" series, but if you stick with it, there is a surprise cameo at the end!
Saint Mark’s Episcopal Cathedral in Seattle, Washington strives to be: a house of prayer for all people, where we worship God and proclaim the reconciling Gospel of Jesus Christ; a loving, welcoming, inclusive community that nurtures faith, encourages service, and integrates social and environmental justice into our lives; a sacred gathering place for the Diocese of Olympia and the broader community in times of crisis, sorrow, and celebration.
Saint Mark's Cathedral is part of the Episcopal Church, and as a cathedral, serves as the seat of the Bishop of the Diocese of Olympia.
