The following comes from a September 15 Traditional Latin Mass Community of Saint Mary Magdalen blog post:
The Solemn High Mass (Extraordinary Form) to be offered by the FSSP as part of the conference program for the Society for Catholic Liturgy has been moved.
Previously scheduled at the Cathedral of Our Lady of the Angels, it will now be at Our Savior Parish at USC Caruso Catholic Center located at 844 West Thirty Second Street, Los Angeles, CA 90007. It’s quite a phenomenal church, built recently and quite beautiful.
The Mass will be on Saturday, October 1st at 8:00 a.m.
