On a chilly December evening in Jerusalem, Yitzhak, a young ultra-Orthodox man, and a few of his friends stand outside the Abiya Beit Midrash, a community center and study hall, waiting for the musical event to begin. In the small hall, Sinai Tor tunes the instruments as he plays the beginning of a well-known Jewish song in a progressive jazz arrangement.
As the music starts, the hall slowly fills up. At first, the young men sit with their arms crossed but soon they start moving their heads to the sound of the music; some start clapping and by the end everyone sings at the top of their lungs. “I felt as if I was floating on a cloud,” Yitzhak, who asked that his real name not be used, told Al-Monitor after the performance.
