From patriotic tunes to plaintive hymns, American music has always been stirring and emotional -- who doesn't feel a rise in his chest when the National Anthem is played or a catch in his throat when he hears "Sweet Low, Sweet Chariot"? In the Chamber Music Society of Lincoln Center's concert American Visions, composers will skillfully incorporate different aspects of music for an unforgettable performance. From Ives' "The Things Our Fathers Loved" to Crumb's masterful collection American Songbook II: A Journey Beyond Time, the evening at Chicago's acoustically pristine Harris Theater for Music and Dance in Millennium Park will be a showstopper.
