As is generally known, opposites attract. Jérémie Zwahlen and Félix Bergeron, both 33 years old, sit in a café in Lausanne, discussing their project to redefine the long tradition of choral music with the aid of electronic experimentation. Bergeron also uses the conversation about this project for a brainstorming session. Exactly as it should be for a drummer, when the rhythms become more complex, he accurately describes more and more options of how it would be possible to combine old and new, traditional and avant-garde. Zwahlen listens with stoic calm, from time to time making his own contribution with incisive sentences. He does not seem to be a stranger to this kind of dialogue. “Félix is like an extremely strong cigarette and I am the super-filter that is used to smoke it,” reckons Zwahlen and both of them laugh.
