The members of Psophos quartet are Ayako Tanaka, Cécile Grassi, Bleuenn Le Maître and Ingrid Schoenlaub, four young talented artists who conceive their musical collaboration as a conversation in which every participant makes their contribution without imposing his personality over the others.

In this film they tell us about their work, starting from their master Paul Katz, the violinist of the Cleveland quartet.
