Talented musician Ina-Ich is back to share another song with us. Her live acoustic performance of “Libre comme l’eau” shows off a more classical side to her music, and treats us to a heartfelt and powerful tribute about roots, identity, and the notion of freedom.

In her first hit single, "Dernière Danse" (Last Dance), Indila shares her troubles, her loneliness, and her sense of rejection in the big city of Paris. Her sweet suffering (douce souffrance or douce France) is a melancholy echo of classic French songwriting, underlining her struggles and lending pathos to her courage.

"S.O.S." is the third single by French R&B singer-songwriter Indila from her album Mini World. The music video was shot in Greece and the song was released in 2014. Indila's sweet, melancholy voice seems perfect for this song, a cry for help from within her "kingdom of pain."
