On Sunday, August 14 at 5:00 p.m. all are welcome at a service of Organ Vespers for the Feast of St. Mary the Virgin. Guest organist Barbara Raedeke leads this service of candlelight, chant, and organ music of French Baroque composer Louis-Nicolas Clérembault and J. S. Bach. Chants will be sung from a French Baroque edition by Guillame-Gabriel Nivers. Dr. Raedeke is on the faculty at Washington University and is the organist at St. Mark’s Episcopal Church. This service concludes our year-long celebration of the 20th anniversary of St. Peter’s Mander organ.
