For the past four years a small film crew has been traveling the world with recording equipment and cameras in search of inspiration.
The film below is an example of their output - more than 35 musicians from at least four continents harmonising in an inspiring virtual global band, epitomising the connection of diverse and disparate humanity through music.
South Africans featured include Vusi Mahlasela from Mamelodi, Sinamuva and Bhekani Memela choirs from Umlazi, and Pokei Klaas from Gugulethu on upright bass.
