The Irvine High School Choral Department plans to premier three original songs at this week's “Concert in Spring.” The show, set to start at 7 p.m. Thursday at Irvine Presbyterian Church, will feature all five Irvine High choirs, as well as the Venado Middle School choir, performing works by living composers. One of those songs, Thomas Cabaniss’ “Celestial Fire,” was originally commissioned for an ensemble in New York City. But the piece was sent out west on the reputation of Irvine High’s vocalists, according to Choral Director Tina Glander Peterson. You can read more in this Orange County Register feature. (Subscription required.) Two other original songs will also make their debut, one composed by Irvine High sophomore Sean McNamara and another written by retired Woodbridge High Choir Director Ron Soderwall. Concert tickets are $10 and can be purchased at the venue, which is located at 4445 Alton Parkway, Irvine. For more information, visit www.ihschoralmusic.org.
