Rose Mercie has existed since 2013. More than a fictional female personality, we can say that it is a rock band with multiple influences or a team of witches who make a very personal trance based on improvisation and who exchange ideas, instruments according to their desires. Their first album, recorded in their friends' living room in Villejuif by Cyril Harrison, was released in 2018. In September 2020, the second was recorded, still with Cyril but in the studio this time. The third album symbolizes what they have become through concerts and years of complicity with simple and essential musical ingredients. Fruit of wanderings and discoveries between Montreuil, Portel-des-Corbières and Mexico City, this opus is called '¿Kieres Agua?' and it is released as an international co-production with Jelodanti Records (Paris) and Celluloid Lunch (Montreal).
