In Hong Kong it's normal for the past to be eagerly forgotten as life in this neon-doused city moves on. But sometimes remembrance is a form of catharsis, especially for the women of the Weitou people, who were among Hong Kong's original settlers. For generations they protested their arranged marriages with proud songs on their wedding nights - "bridal laments" that have now been brought back to life as an electro-infused anthem by artist Rainbow Chan. Directed by Anne Berry, the music video 'Seven Sisters' reimagines this ritual in a 100-year-old walled village, and even features some of the original brides that first learned these ancient songs.
