The GW Chamber Choir’s Nov. 20 performance of “From the Outside Looking In” marks the first time a GW Music Department group will perform at the John F. Kennedy Center for the Performing Arts. “This opportunity is amazing,” senior GW Chamber Choir member Jeff Stern said. “Of course, it means the pressure’s on, but I think we’re all up for the challenge.”

Featuring composers from various styles and periods, the Saturday concert is one in which “the composers are looking at a culture that is not its own,” choir director Matthew Mehaffey said. “I think the program is very diverse and has something that everyone will like.”

Stern called the program “extremely varied,” featuring Renaissance to modern pieces and even a few American spirituals. Founded in 1986, the 40-member GW choir is “a wonderful blend of talent, in that we are from all parts of the country. We have many different vocal styles that make a very unique sound,” Stern said. The group has toured both nationally and internationally and participated in local concerts and television programs.

The performance also includes a guest appearance by the Washington String Quartet, GW’s ensemble in residence.

“They’re a very talented group,” Stern said of the quartet. “We really appreciate their efforts in creating this performance and hope we can work with them again in the future.” Also accompanying the group is Alice Mikolajewski, assistant director of the choir and piano instructor at GW.

Mehaffey said he reveres the chamber choir as “a select ensemble, the best singers at GW in my mind.”

“From the Outside Looking In” is $12 for students and seniors, $25 general admission. Tickets can be purchased online at www.kennedy-center.org or by phone at (202) 467-4600.
