Quilapayún are an instrumental and vocal folk music group from Chile and the most lasting and influential exponents of the Nueva Canción Chilena (New Song) movement. Formed in Chile during the mid-1960s, the group became inseparable with the revolution that occurred in the popular music of the country under the Popular Unity Government of Salvador Allende. Since its formation and during its forty-year-long history - both in Chile and during its lengthy period of exile in France - the group has seen modifications to its personnel lineup, to the subject and content of its work, and controversy regarding irreconciliable differences with the current and former group director; which has led each to maintain a distinctive - yet equally impressive - Quilapayún ensemble: one in Chile (named: Quilapayún-Histórico) and one in France (named: Quilapayún-French-Faction).
