LEWISTON — The Lewiston Public Library will resonate with the sounds of the season on Wednesday, Dec. 16, when the Lewiston High School Chamber Singers give a free public concert. Titled “O Tidings of Comfort & Joy!,” the event is scheduled for 7 p.m in Callahan Hall on the library’s third floor.

The hourlong program is a festive mix of traditional Christmas music and other songs of the season, both old and new, according to group director Rebecca Poppke.

“Hiney Mah Tov,” which celebrates Hanukkah, the rhythmic Nigerian number “Betelehemu” and the Gloria from “Missa Kenya” will add a multicultural flavor to the evening.

The singers will take a decided detour from the holiday theme with their rendition of the big band-era jazz classic “Take the A Train,” as well as a new composition by Colin Britt, who graduated from Edward Little High School in 2003 and is currently enrolled in the Master of Music program at Yale University.

While the entire 35-voice Chamber Singers ensemble will present most of the pieces on the program, a 12-member subset of that group, Diaboli Musicae (which translates to “Devils of Music,” a lighthearted twist on the LHS Blue Devils sports moniker), will perform many of the more upbeat, contemporary numbers. Accompaniment will be provided on piano and percussion, with a few other “instrumental surprises,” said Poppke.

Though there is no charge for admission, audience members will be invited at the close of the show to contribute to the singers’ “On the Road” fund, to help defray expenses for the group’s biannual, out-of-state concert tour planned for next spring.

The library is at 200 Lisbon St. For more information on the concert, call 513-3135.
