Exactly 800 years ago the most important interreligious encounter and an early rapprochement of two religions took place: Francis of Assisi and Sultan Al Malik Al Kalim met on the fringes of the Crusades. The Pera Ensemble and Mehmet Ye?il?ay take a look at the historical meeting. They show how music can be used by the most diverse peoples and cultures. religions, and create a creative synthesis of both worlds. "This encounter had a lighthouse effect. and was, in my view, the beginning of a dialogue between religions. Today, the message is more important than je: we must talk to each other about our faith, peacefully and with respect!" (Mehmet C. Ye?il?ay)
