Mandoo was born under the impulsion of Pierre Vanier and Esther Ben Daoud, a duo both on stage and at home. One is a bassist and a singer, the other is a pianist and an arranger. They played together for several years in diverse jazz, pop or rock groups. In 2003, they decided to be the masters of their own fate and created their own group. First a sextet inspired by the soul-funk American repertoire, the group progressively evolved along a more personal line.
After several changes, Pierre Vanier, Esther ben Daoud and Fabio Marchesan, a guitarist and lifelong friend, invited drummer Moussa N'diaye (Tarace Boulba), saxophonist Olivier Laudrain (Mory Kante), trumpeter Vincent Payen (Cabaret, Alpha Blondy) and Audrey Lesieur (Lyrics writer) to join them.
As years go by, Mandoo's experiences and collaborations keep increasing. They play in all Parisian clubs (Etage, Balle au bond, Belvédère,...), give one concert after the other in the Club Med villages in France and abroad (Athenes, Marrakech, Kemer...) and for professional events.
At the end of 2007, the group got into a studio to record their first five titles at PFL Studios with Xavier Duthilleul and Pascal Santos (Minu Cinelu).
