Olivier Toussaint, was born in Paris, in a family of classical musicians. His great grandfather, Gilbert Duprez was a very well-known Opera singer. His grandparents were both opera singers, and his mother was a concert pianist who played in big orchestras in France.
On the insistence of his mother, he studied Economics and Social Sciences at University in Paris. But as soon as he graduated, he was back making music. He worked professionally as a singer and musician, playing guitar. At the same time he was involved in writing music for television and the cinema.
Classical music was a part of his life due to his family background, but it did not fit to his musical expectations. Other than classical music, he was very interested in jazz, easy listening, semi-classical, and pop music.
