Al gran sole carico d'amore (In the Bright Sunshine Heavy with Love) is an opera (designated as an 'azione scenica') with music by Luigi Nono, based mainly on plays by Bertolt Brecht, but also incorporating texts of Fidel Castro, Che Guevara, Karl Marx, and Vladimir Lenin.

It premiered at the Teatro alla Scala on 4 April 1975, conducted by Claudio Abbado.

[1] In addition to vocal soloists, chorus and orchestra, the work incorporates taped sounds.

The principal characters are women from those periods, who perish in an attempt to stop the violence of their times.
