It's not only about uniting the young people, but it's also uniting our community at large," said Uniting Voices Chicago President Josephine Lee. "Our vision is to create a more harmonious world in a world that is still divided."
What won't change, said teachers and members, is a commitment to education and broadening perspectives.
"In 10 years, 20 years, 50 years, I might have forgotten the music. But, I will never forget the people that have shaped me in this organization," said Wren Pfetcher, a member of Uniting Voices Chicago.
The organization, which has performed on five continents, was in Egypt over the summer. In this upcoming season, hundreds of concerts are planned, including collaborations with Lyric Opera and Chicago Opera Theater.
