This SACD, with compositions by Louis Moreau Gottschalk, George Gershwin, Samuel Barber, Frederic Rzewski and Philip Glass, presents a cross-section of North American piano music from 1850 to 1980. It offers the listener the possibility to become immersed in a fascinating musical cosmos that is, above all, notable for its stylistic variety. This is characteristic of American music's search for its identity from the very beginning of its history: a lack of historical references is replaced by a plethora of ethnic-social phenomena and the principle of permanent cultural exchange.
