Since his arrival in Paris 15 years ago, and assisted by Patrick Tandin Productions, Raul Barboza gained international repute. Through records, DVDs and concerts on the world's most prestigious stages, Barbaoza globally legitimized his Indian-inspired accordion and became the major ambassador of ChamamE, the expression of a natural life-style using musical rhythms and improvisation.
