Washington University Choirs present “Dream and Journey,” Sunday, April 30, at 7:30 pm. The program explores the topic both literally and figuratively, with texts by William Shakespeare, Bai Juyi, James Agee, Langston Hughes, and William Butler Yeats. In addition to classic composers such as Palestrina, Brahms, and Barber, the concert includes works by Moses Hogan, Ola Gjeilo, Alice Parker, Abbie Betinis, Ricky Ian Gordon, and St. Louis native Rollo Dilworth. This is the Chamber Choir’s final performance before they embark on their own journey, their first international tour. They will visit Latvia, Lithuania, and Estonia as a part of Music Celebrations International’s American Celebration of Music in the Baltics.
