[2] Roth graduated from the Conservatoire National Supérieur de Musique, where his teachers included Alain Marion for flute and János Fürst for conducting.

[4] In 2003, he founded Les Siècles, an orchestra which performs on instruments appropriate to the period of composition of each piece, from late Baroque and Classical to 20th century music, such as Ravel.

To mark the centenary of The Rite of Spring in 2013, the orchestra performed the work on period instruments at the BBC Proms and the Alte Oper, Frankfurt.

Roth and Les Siècles have devised their own television series for France 2 entitled Presto!, which ran for three years and attracted audiences of over three million viewers.

[3] Roth has involved Les Siècles in community music initiatives, including sponsorship of orchestra and choir groups in the Société générale.

[19] In January 2018, Roth was nominated "Artiste associé" at the Philharmonie de Paris, which is also linked to his work with the children's orchestra Démos, an initiative based on the model of El Sistema.
