“The song on which the variations is based is one of many that emerged from the Unidad Popular coalition in Chile between 1969 and 1973, prior to the overthrow of the Salvador Allende government. Rzewski composed the variations in September and October 1975, as a tribute to the struggle of the Chilean people against the newly imposed repressive regime of Augusto Pinochet; indeed the work contains allusions to other leftist struggles of the same and immediately preceding time, such as quotations from the Italian traditional socialist song “Bandiera Rossa” and the Bertolt Brecht/Hanns Eisler “Solidarity Song”.“
