For this second edition of his guide to the more adventurous evolutions of music since 1945, Reginald Smith Brindle has added a new chapter reviewing developments in the decade since the book first appeared. 'A lively, well-organized, lucid, historically aware, and concise survey of the techniques, aspirations, interaction, and sociology of the avant garde as it has evolved since the end of World War II...a book that might easily be used as a text for an undergraduate course. Moreover, it could, with careful and intelligent application, be used for study by non-musicians.' Notes reviewing the first edition
