os Sinvergüenzas, musical ensemble, was born as a music experiment in Mérida, Venezuela in 1999. Its musicians created a compilation of the folk music, and then they made some adaptations to the new style of interpretations. Later, in February 2000, they founded this ensemble with a concert which took place in the Aula Magna of the University of Los Andes; since then, they have made an important work when it comes to compositions and musical arrangements of the Venezuelan folk music genre.
