Folk revival
Contributors to Folkopedia frequently mention the "Folk Revival". What they normally mean is the quite sudden increase of interest in traditional song and music starting with pioneers in the 1950s and establishing itself in the 1960s with an explosion in the number of clubs and later festivals. Much has been written about the reasons for this, and this site will probably have a major section. The revival is sometimes called the "second folk revival", the first having been the major collecting activities of the 1890s and early 1900s, including the formation of the Folk Song Society in June 1898.
