Working with the Chileans on the 'Alianza' tour and album of the same name had a profound impact on Beer and Knightley. Whilst informing their rhythmic language and musical sensibility, it also inspired them to add the cuatro to their repertoire. The Chileans' awareness of music’s power to educate and inform (and the risks that they took to perform it), hit home with Beer and Knightley. "In our society people can make political statements in song and no one will threaten you. But for them, just getting together and playing ordinary folk songs (meant) risking arrest, imprisonment and exile."
