The push towards a national, anti-imperialist sound came with the pseudo-dystopian mindset that prevailed in the Sweden of the 1960s, something that stood in dire contrast to the 'peace and love' ethos of hippy idealism.

In the mid-60s, large parts of the inner city of Stockholm, the site of many houses and homes, were bulldozed to pave way for the new architectural wave of the future: towering skyscrapers, "glass and concrete".

The album, with its telling opening track of Dies Irae played on horns, aims to reflect the loss of nature in the name of human advancement.

To follow this theme, the group changed its name from Pärson Sound to "International Harvester", taken from the American company that manufactured agricultural machines.

The track is an ode to one of Persson's main influences, ecology philosopher and food industry researcher Georg Borgstrom.
