In Geneva, once a year, children and adults in pyjamas and socks spend a night at the opera listening to music. From 8 pm, they wander its fresco-covered foyers, listen to performed music and spend the night dozing in an auditorium lit up like a starry night. Among them are many families with children who marvel at the giant mirrors with gilded frames, the angels and nymphs painted above, and, of course, some music. Italian pianist and performer Marino Formenti says he enjoys playing various compositions "Ranging from baroque to Chopin, to rock music, Pink Floyd, the Beatles and other things".
