Folk, As In Music Of and By the People

"There are no nightingales in these songs, no flowers -- the sun is rarely mentioned, their themes are work, poverty, hunger and exploitation. They should be sung to the accompaniment of pneumatic drills and swinging hammers, they should be bawled above the hum of turbines and the clatter of looms for they are songs of toil, anthems of the industrial age..."
-- Ewan MacColl in The Shuttle and the Cage (1954) as quoted in Electric Eden by Rob Young (2011).
