The Indri lemur, also known as the singing lemur, can be found only in Madagascar’s rainforests. Famous for their eerie, melodic calls, they are one of the few primates that sing and, as it turns out, they have a surprising relationship to rhythm - one that’s very similar to our own.

After hearing news of these unlikely rhythmic capabilities, Georgie Styles ventures into one of the most biodiverse yet threatened ecosystems on Earth to capture the haunting songs of this critically endangered species, as they echo through the treetops. But as she goes deeper into this tale of survival and song, she discovers a hidden female history.

So what can the Indri lemur tell us about the origins of music?

Providing us with the first-ever evidence of complex vocal abilities that exceed those of any other mammal, besides humans, the Indri reveals clues to our own evolutionary journey and offers us a rarely told perspective.

With contributions from primatologist and conservationist, Dr Sylviane Volampeno, primatologist Dr Chiara De Gregorio, researcher Irene Marchesi and a team of Madagascan research guides, A Lemur’s Song connects nature’s melodies to the evolution of music. Through the captivating sounds of Madagascar’s rainforests, the Indris songs and the creative responses of an original score by music artist and saxophonist Laura Misch, Georgie reflects on what sounds can tell us about our world and what we are at risk of losing.
