Draper-based community choir Jubilate performs Mozart's Requiem on Friday, Sept. 11, to mark the 25th anniversary of the Sept. 11, 2001, attacks.

The free concert, titled "Lest We Forget," runs from 7 to 8 p.m. at St. Vincent de Paul Catholic Church, 1375 East Spring Lane, in Holladay, according to the Draper Journal event listing. No tickets or RSVP are required.

The program honors those who died at the World Trade Center, the Pentagon and in Shanksville, Pennsylvania. It also recognizes first responders and local law enforcement and fire and rescue workers.

Jubilate first performed the Requiem in 2002 as part of the global "Rolling Requiem," according to a Utah Public Radio listing. Friday's performance features the chorus, a small orchestra and a candle-lighting dedication.

Jubilate's concerts are supported in part by the Salt Lake County Zoo, Arts & Parks (ZAP) program. The choir's next performance is Saturday, Dec. 5, at the same church.
