Shortly after 9/11, British documentary maker Jasmine Dellal began filming a diverse band of musicians on tour across North America. They came from Spain, Macedonia, Romania and India and made a special kind of music – so special that Dellal began shooting in India using her Mastercard as principal backer until a grant came through. The six-week tour was punctuated by a wedding, a funeral, an impromptu fishing expedition that caught the attention of local police – and a tale of deep friendships forged on a tour bus, as it made its way across a country shocked to the core by the World Trade Center attacks. Angela Meredith spoke to Jasmine Dellal about ‘Gypsy Caravan/When the Road Bends’ and the power of music to overcome adversity.
