In April of 1939 an unusual event occurred on a Los Angeles rooftop: nineteen people gathered to hear an all-Bart#65533;k program of chamber music. Thus was launched the now-famous Evenings on the Roof. The concert series later became the Monday Evening Concerts, whose popularity continues to this day. This is the story of that adventurous series, and Dorothy Crawford's graceful telling reveals the changing world of twentieth-century art music. It is also a story of idealism and determination, and of a unique synthesis of talent that could happen only in Los Angeles. Evenings on the Roof were the inspiration of writer Peter Yates and his wife, pianist Frances Mullen. To the Yates's rooftop studio came local and #65533;migr#65533; musicians and composers. Though performers received little financial compensation, composers offered their latest works, and the growing audiences welcomed the challenging new music. Music critic Lawrence Morton joined this endeavor and helped forge an innovative musical community. The series introduced works of Igor Stravinsky, Arnold Schoenberg, Lukas Foss, Pierre Boulez, and John Cage and provided an early venue for Robert Craft, Marilyn Horne, Marni Nixon, and Michael Tilson Thomas, among others. The fascinating contradictions that are part of Los Angeles emerge in this book as well: the city known as both "Lotusland" and "Tinseltown" could also embrace the most challenging music of the Western heritage. Through the vision of Yates and Morton and the devotion of extraordinary artists, music in Los Angeles achieved a rich maturity.
