An Empire Built on Shingle: Britten, the English Opera Group, and the Aldeburgh Festival
Benjamin Britten Studies: Essays on An Inexplicit Art
Britten’s post-war years began an interval in which his energies were almost exclusively focused on building both an empire and the environs in which a living and vital musical establishment could flourish outside London. During the ten years immediately following Peter Grimes Britten not only composed seven of his nine full-scale operas, he also devoted himself to the founding of both the English Opera Group (EOG, 1946–47) and the Aldeburgh Festival of Music and the Arts (AFMA, 1947–48).
