Mark Williams, Organist, with the men of Cantores In Ecclesia, Dean Applegate, Director Organ compositions based on Gregorian chant are heard here, with their chant predecessors performed beautifully by the men of Cantores In Ecclesia, a Portland, Oregon, choir directed by Dean Applegate. From De Grigny to modern French composers, organist Mark Williams plays organ literature clearly showing its plainsong roots and illustrating the debt of composers to the vocal form. The organ used is Bond Organ Builders, Op. 25 of 34 stops and 37 ranks built in 1996 for Holy Rosary Catholic Church in Portland, Oregon, and incorporating 15 stops from John Bergstrom’s Op. 7 built in 1880 for First Methodist Church, Portland.
