Victor Gama composed Rio Cubango (2011). After Rio Cunene composed for the Kronos Quartet, Rio Cubango is the second in the series Music for Rivers. A commissioned work by the Prince Claus Fund and the Amsterdam Fund for the Arts. A composer, musician and contemporary instruments designer, Gama partnered with harpist Salomé Pais Matos and Zapp4 string quartet to premiere the piece at the Concertgebouw in 2011. Victor and Salomé are playing a toha, one of Gama's instruments from the Pangeia Instrumentos series. The toha drew its inspiration from the nest of a weaver bird. It has a totemic significance, hence its name. It has no relation to a cora, neither in sound, playing technic or design.
