Benares, or rather Varanasi (in Hindi)... A city with huge staircases (ghats) leading to the Ganges, a city at the confluence of Hinduism, Buddhism and Islam, which opens up multiple paths of spirituality. "A bath in the Ganges is worth years of yoga. "A single note of music played with accuracy is worth all the asceticism..." These are words that can be heard in the mouths of some Indian masters, but of course it is not just any immersion, any accuracy! Throughout this rich and intense documentary, Yves Billon's camera seeks to make us feel the mystery, because it is more important to feel than to understand. It invites us to the banks of the sacred river, to the maze of streets of Benares, to its mansions and ancient palaces, to meet exceptional musical personalities: the legendary oboist (shehnaï) Ustad Bismillah Khan - at the heart of the film -, the singer Girija Devi, the percussionist (tabla) Lacchu Maharaj, the violinist N. Rajam. A journey in and of itself, as a prelude to the concert by N. Rajam and his family.
