Canto Armonico presents a vespers service for the Nativity of St. John the Baptist here at 5 pm on Saturday, June 15th as a fringe event of the Boston Early Music Festival. A similar service in 2011 was very popular with the attendees, many of whom know vespers music only from the secular concert stage and were gratified to experience it in its proper, devotional context. We are fortunate to have Dr. Ulf Wellner, Kantor of the Jakobikirche in Lübeck, Germany, with us to celebrate the vespers and to join in worship on Sunday the 16th. Dr. Wellner is a specialist in Lutheran music of the sixteenth and seventeenth centuries. This is his first visit to the United States and he is eager to meet everyone.
