Organizers of a concert at the Cathedral of Our Lady of the Angels commemorating the 10th anniversary of the Sept. 11, 2001 attacks expect a sizable turnout for the free event offering a selection of choral works chosen to honor and celebrate the lives of those affected by the national tragedy.The musical program combining voices from the 120-member Angeles Chorale and the 50-member OLA Cathedral Choir is anticipated to draw at least 2,000 people to downtown Los Angeles for the Sept. 11 event starting at 4:30 p.m.Angeles Chorale artistic director John Sutton will conduct meditative choral works including “Requiem,” by Gabriel Fauré; “In Remembrance” by Eleanor Daley; “Sleep,” by Eric Whitacre; and “Sing Me To Heaven,” by Daniel Gawthrop.Sutton approached Cathedral music director Frank Brownstead in May about hosting the remembrance event on the 10th anniversary, which he called “an important time to look back on those tragic events and use the power and elegance of choral music to give perspective, meaning and understanding as we look at how the events of 9/11 have shaped us.”“We thought it was a great opportunity for the community,” said Sal Soria, Cathedral organist who will accompany the choir along with a trumpet player. He noted that the Cathedral was the site of the first memorial observance a year after the attacks, as part of the planned nationwide events and observances.“The Cathedral had just opened (on Sept. 2, 2002),” said Soria. “The interfaith remembrance service of prayers and music was very emotional and healing for a lot of people.” He remembered many attendees singing the lyrics to “What the World Needs Now Is Love,” along with the choir as the song’s musical composer, Burt Bacharach, accompanied the singers on the piano.Msgr. Kevin Kostelnik, Cathedral pastor, who led 400 construction workers in an impromptu prayer service for 9/11 victims at the Cathedral site ten years ago (as the Cathedral was entering its final stages of construction), said the upcoming concert is an opportunity to gather and reflect.“We are all connected as brothers and sisters in the nation, so it’s important that we pause and remember and work toward peace,” said Msgr. Kostelnik. “Music is a way to bring people together to remember the victims, first responders and all those in the military currently serving in wars overseas.”—Paula Doyle
