To assert its Corsican identity, the group's name refers to a kind of fern that grows on the island.

In 2009, they performed in France, Germany, Poland, Ireland, Brazil, in the Baltic States, Belgium, Italy, and Austria.

The group A Filetta was founded in October 1978 in Balagne by Michel Frassati, a young teacher, joined by Tumasgiu Nami, apiculturist.

This association whose first objective was to contribute to the salvation of the Corsican oral heritage was linked to the Riacquistu mouvement.

The group is currently composed of 6 singers: "A Filetta - tradition et ouverture Archived 2011-10-21 at the Wayback Machine", by Jean-Claude Casanova - Colonna Editions, Ajaccio, 2009
