Yvon Demillac studied guitar with Carel Harms and Alexandre Lagoya. He has taught at the conservatoire régional d’Angers (France) since 1979. Meanwhile, he has pursued his musical activity especially in the repertoire for two guitars; flute, guitar; chamber music and the show «Platero y yo» staged by actors. In 2006, his encounter with Sylvain Lemay is decisice; it now gives him new perspectives on the writing for his instrument. His works are published in Canada by Productions d’OZ and in France at the Billaudot, Combre, Lemoine and Fuzeau editors.
