What can my heart do? is a song that invites us to ask ourselves, to look around us, to look at the natural disasters, the inequalities, the oppression, the war, the children. It is a call to rethink our message, to reflect. As musicians, to sing that message. It was composed by the Argentine Angeles Mendoza, as a copla of her folklore, in Spanish language. Australian singer Floyd Thursby is called upon to take the message to the world.
