Benjamin de la Fuente and François Cotinaud are here, in keeping with the long tradition of the "open work" where the relation between interpret and composer is redefined.

François Cotinaud is a soundpainter, founder of the Soundpainting Festival and theoretician of the soundpainting. He recorded with the Klangfarben Ensemble the first soundpainting disc ever recorded in France: Monologue de Schonberg. 

In February 2016, he briefly directed the Ensemble Intercontemporain, in a suite of pieces by François Rossé. The experience, which had a great reception, is at the origin of the "Mosaïque" project.

Throughout his career Benjamin de la Fuente has created bridges between writing and improvisation. He has composed for contemporanean ensembles but also for the Orchestre National de Jazz. He is himself well versed in improvisation, notably with his band Caravaggio.
