Drawing on a range of sources and fields, the rich life story of this polymathic composer. This groundbreaking biography offers fresh perspectives on the life, ideas, and music of French twentieth-century composer, organist, and ornithologist Olivier Messiaen. Drawing from previously unexplored sketches and archival material, the book seamlessly combines elements of biography, musicology, theology, philosophy, psychoanalysis, and aesthetics to present a nuanced perspective on Messiaen?s work. Robert Sholl explores the profound impact of Messiaen?s devout Catholicism, which found expression through his work as a church organist, his engagement with birdsong, his interaction with Surrealism, and his profound influence on major musical figures of the latter twentieth century. Unlike previous biographies, this book also considers the perspectives of Messiaen?s contemporaries and students, providing a comprehensive understanding of his life and artistic legacy.
