Muntaner founded the C-Ktre studio in Marseilles in 2002, harnessing his twenty years experience of experimental work in graphic design, illustration, fine art, poster design and film directing. Muntaner is highly respected in the performing arts scene, having created visual identities for the Merlan Scène Nationale theatre in Marseilles, the Centre Chorégraphique in Le Havre, and the 'Jazz des Cinq Continents' festival, amongst other performing arts projects. Muntaner continues to reinvent himself in recent work for clients such as the Ballet Preljocaj and the major 'Marseilles Provence 2013' European Capital of Culture initiative.
