Osvaldo Fattoruso (12 May 1948 – 29 July 2012) was a Uruguayan musician.
He introduced rock in Latin America with his band Los Shakers, and also created a fusion between jazz, rock and African rhythms together with his brother Hugo Fattoruso in Opa (Uruguayan band).
After living several years in the United States, he returned to Uruguay in 1981 and performed live with Opa at the Cine Teatro Plaza, a historic performance in his country by a band that was already a cult favorite.
