In my readings of A Guide to Musical Styles: From Madrigal to Modern Music by Douglas Moore, I came across this quote by the author:
“Romanticism, however, cannot be defined to a single period of music. Since it is primarily a point of view, a youthful, experimental naïvete on the part of the artist, it is found in all ages - even, with apologetic mien, in our own. The interests of the Romantic are wide. They include literature, history, philosophy, the world of nature, and the spirit of man, all of which are brought into the vocabulary of art, which is altered and expanded in the process. The artist, conceiving himself as more than artist, sees himself as a spiritual leader of the people, a sort of interpreter of the universe. He refuses to fetter his imagination with classical doctrines. So sure is he of his role of prophet that he sometimes forgets his duty as craftsman.”
I reckon that means that we have Rachmaninoff to blame for The Peace Piece.
