Initially an organization of people who worked on Capitol Hill, the group has since expanded its membership to 80 singers from diverse professions and backgrounds. David Simmons, the current Artistic Director, joined the chorus in 2006. In addition to its programs at the Atlas Performing Arts Center, Congressional Chorus has sung for several occasions at the White House and at numerous functions on Capitol Hill that have included presidential inaugurations and the Capitol Christmas tree lighting. Other notable venues have been the Kennedy Center, Lincoln Memorial, Gunston Hall, the Lyceum, Union Station and the National Building Museum, where the chorus was featured on NBC’s televised “Christmas In Washington.”
Over the years, the chorus has also commissioned a number of compositions in a dedicated effort to promote and advance the creation of new American choral works. SINGING AMERICA'S SONGS: A Silver Anniversary Concert featured the world premieres of two works commissioned in honor of Congressional Chorus’ silver anniversary: Be It Therefore Resolved by Joan Szymko, a nationally acclaimed choral composer from Portland, Oregon and Dreams by Chris Urquiaga, a student at the Eastman School of Music. In November 2011, the Chorus performed an expanded version of One Land by Rand Snell, which was commissioned for the 20th anniversary.
