Les Luthiers is an Argentine comedy-musical group, very popular also in several other Spanish-speaking countries such as Paraguay, Guatemala, Peru, Chile, Ecuador, Spain, Colombia, Mexico, Uruguay, Bolivia, Cuba and Venezuela. They were formed in 1967 by Gerardo Masana, during the height of a period of very intense Choral Music activity in Argentina's state universities. Their outstanding characteristic is the home-made musical instruments (hence the name luthiers, French for "musical instrument maker"), some of them extremely sophisticated, which they skillfully employ in their recitals to produce music and texts full of high class and refined humor. From 1977 until his death in 2007, they worked together with Roberto Fontanarrosa, a renowned Argentine cartoonist and writer.

Here Les Luthiers is a recital of the Argentine group of informal musical instruments Les Luthiers, made especially for the 45th edition of the Cosquín Folk Festival. It was presented for the only time on January 28, 2005, at the Plaza Prosper Molina in the city of Cosquín, Córdoba, Argentina, traditional venue of the festival.1
