Most of the singing, however, was performed by the monks of the Abbey. They performed the service, singing plainchant in Latin. I had thought that after Vatican II, most English speaking Catholic churches used English for the services. However...
The monks sang very nicely, processing with incense, wandering all about the church.
The small group from the Chicago Choral, about 6 men and 6 women, sang very well choral music of Tomas Luis de Victoria. The conductor is Bruce Tammen. Mr. Tammen has an unusual technique of conducting this type of music. Everything is a downbeat.
All in all it was an interesting experience.
