Le Fil is the second album by French singer–songwriter Camille. The title translates as “The Thread”. The album features a low-level drone (a B tone) in the background of every song, which Camille has described as “her note”. Camille has stated that many people returned the record, thinking this sound was a fault in the recording.

The album was first released in 2005, and reissued in 2006 in the United States, the UK and Australia with four extra tracks. The final track on the original version, “Quand je marche”, runs for close to 39 minutes. The actual song is only four minutes in duration, but the tone extends for over 30 minutes after it has ended. The final 30 seconds contain Camille speaking in French. This extended ending was cut from reissues featuring bonus tracks.

It has been most frequently compared to Björk’s Medúlla, for Camille’s use of her voice as an instrument in innovative ways.

In 2008, the eighth track on Le Fil, “Senza”, was used by Ford in televised adverts for their Kuga SUV. The advert premiered at half time of the 2008 UEFA Champions League Final, opening up a new Pan-European audience to Camille’s work. It has continued to air on networks across Europe throughout Euro 2008.

In 2010, the track “Ta douleur” was featured in the Saturday Night Live sketch “Les Jeunes de Paris”.
