3. Ives Crawford Seeger Riegger Ruggles Rodgers Gershwin"The history of American composition at the beginning of the 20th century revolves around an absent center," states Alex Ross, music critic for the New Yorker, and even titles the corresponding chapter in his bestseller "The Rest is Noise" "The Invisibles." This refers to composers such as Charles Ives, Wallingford Riegger, Carl Ruggles and others who had to work hard to establish an identity as American composers. Barbara Hannigan has made it her mission to bring these "invisibles" back to light. After intensive research in the Library of Congress, she presents a program that is probably unique in its form. It shows American music between 1900 and 1945 as if through a magnifying glass: from radical simplicity to radical dissonance to the fusion of classical and popular music, which reached its peak on Broadway. A picture of musical diversity that must necessarily remain incomplete, but even in this form allows fascinating and surprising insights. Hannigan's particular focus is on the individual, edgy, rebellious voices that sought their own expression and broke new ground.
