The world's most remarkable musical instrument is the human voice, and the University of Georgia's choral ensembles bring together on stages here and abroad some amazing voices. Here are some of Bob Brussack's photographs of the fall 2009 concert by UGA's concert choir, its chorus, its symphony, and alumni soloists. The music you'll hear is not from the concert. Perhaps you can imagine how glorious these voices were in Hodgson Hall that evening.
