The Mass of Thanksgiving & Remembrance to honor law enforcement and emergency personnel will take place Sept. 11th at the Cathedral of Saint Paul. The event begins at 4:30 p.m. with a civic commemoration, followed by mass at 5 p.m..

Trinity Wall Street (the 'Ground Zero' church) commissioned musician Robert Moran to compose a requiem for their youth chorus to commemorate the 10th anniversary of Sept. 11, 2001.

The Cathedral of Saint Paul's new Director of Sacred Music, Robert Ridgell, conducted the children's choir for the recording of the "Trinity Requiem," to be released by the American Composers Forum on the Innova label Sept. 6.

Ridgell, formerly the Music Director at Trinity Wall Street, assumed his new role as Director of Sacred Music for the Cathedral in July.
