From wikipedia:
The band, which mixes African and Latin traditions, was formed in 1991 by Luca Morino and Fabio Barovero, from the Piedmont region of Italy, and Bienvenu Tatè Nsongan, from Cameroon. The band's name has a double meaning: it references the Kenyan Mau Mau uprising against British colonial rule, and, in the Piedmontese language, Mau Mau designates "people who come from afar".
