John Cowley - Böcker

Starting from the days of slavery and following through to the first decades of the twentieth century, this book traces the evolution of Carnival and secular black music in Trinidad and the links that existed with other territories and beyond. Calypso emerged as the pre-eminent Carnival song from the end of the nineteenth century and its association with the festival is investigated, as are the first commercial recordings by Trinidad performers. These featured stringband instrumentals, 'calipsos' and stickfighting 'kalendas' (a carnival style popular from the last quarter of the nineteenth century). The emphasis of the book is on history, and great use is made of contemporary newspaper reports. colonial documents, travelogues, oral history and folklore, providing an authoritative treatment of a fascinating story in popular cultural history.
