Musical performance
With Sisters! Winter Family extends the musical and textual performances conceived in situ for churches, including the Brothers series, to Notre-Dame de Sion Cathedral. The experiment began in 2006 in the Church of Saint Elizabeth of Hungary in Paris, as part of the programming imagined by Maxime Guitton under the name Ali-fib. Borrowing the form of a secular service, these performances, featuring Xavier Klaine at the organ while Ruth Rosenthal chanted texts in various languages including Hebrew, have since been performed in New York, Jerusalem, Bologna and elsewhere.
