Artists at heart

Born from beautiful encounters with prestigious musicians of international renown, the Quartem agency promotes its artists in France and abroad, drawing inspiration from their individual trajectories while respecting their musical and human values.

The artists’ insatiable curiosity, their thirst for discovery, generosity, appetite for sharing with the public, and integrity, are the driving force of the Quartem agency, who assists them daily in the realization of their projects.

The art of sharing

Listening above all to the musicians it accompanies, the Quartem agency endeavours to provide concert promoters with custom solutions, taking into account administrative and financial aspects as well as their repertoire expectations, drawing upon the breadth of the artists' repertoire.

In a constructive spirit of dialog and exchange, the Quartem agency develops and fosters a relationship of trust, concentrating on supplying artists and promoters with answers closest to their needs, conceiving with them, hand in hand, suitable proposals.

Excellence and trust are the pillars of the Quartem agency, whose ambition is to contribute to creating moments of beautiful emotion shared between the musicians and the audience.
