Self-taught musician, Mathias composes on his guitar from the age of 6, passionate about classical music, and more particularly Ravel, then he discovered jazz... At 18 he learned flamenco among the gypsies. He develops and invents his own particular techniques with the right hand (rasaguedo) which he will use on stage or in his compositions. In love with traditional music, he learns to play instruments from all around of the world: Morin khuur, Igil, fiddles, jew’s-harp, berimbao, flutes and percussions of all kinds, saz, oud, banjo feed his orchestrations. Mathias likes to divert, mix, reinvent the artistic universe of these instruments far from the paths of their origins by superimposing his voice sometimes voluptuous, sometimes diphonic. He composes regularly for films and documentaries. Mathias Duplessy creates the project "The Violins of the World", surrounded by Guo Gan, Chinese master of Erhu, Aliocha Regnard, virtuoso of the Swedish Nyckelharpa and Enkhjargal Dandarvaanchign, one of the great Mongol masters of the “horse-headed fiddle”. In 2011 Mathias met Jeremy Jouve who would become the ambassador of his pieces for classical guitar, now played by the greatest international soloists. Insatiable, curious, Mathias Duplessy never ceased to diversify his sources of inspiration, and to collaborate with artists from all traditions, thus breaking down the boundaries of genres, leading to an unparalleled style.
