Tuca (born Valeniza Zagni da Silva, 17 October 1944 - 8 May 1978) was a Brazilian guitarist, songwriter, and singer.

[4] She was playing and singing in a Brazilian restaurant in Paris called La Feijoada when Françoise Hardy first encountered her music.

As critic Diego Olivas wrote, “A brief trip to Brazil had shown Françoise that through Brazilian music she could escape her cutesy, pop image.

Richie Unterberger quoted Hardy as saying, “It’s the only album that I re-listen to regularly, and I find that it still holds a punch.”[6] That same year, Tuca played guitar and did arrangements on Dez Anos Depois by Nara Leão, another Brazilian musician who had exiled to Paris for political reasons.

[2] She signed with the Brazilian Som Livre label, but recorded her last album, Dracula, I Love You, at the Château D’Hérouville Studios outside of Paris.
