In 2009, during the so called 'credit crunch', the G20 group of nations met in the United Kingdom.
In response, groups of anti-capitalists and anarchists demonstrated in central London. They were unhappy with the economic situation throughout Europe, and wanted to send a message to their leaders.
The demonstration spiralled out of control; banks were broken into; protesters were beaten, and an unarmed bystander was killed by police. As a budding photojournalist at the time, Billy Macrae was present, and documented numerous flash-points during the day.
Five years later, with the UK economy seemingly emerging from the financial crisis, he returned to the scene to re-photograph his images in the same spots that they originally occurred.
The effect of viewing two parallel realities side by side is surreal, jarring, and eye catching. The pictures are however open to interpretation - perhaps as one man's fumbling attempt to make sense of fading memories, or as a warning about the kind of activities that may one day reoccur on the seemingly tranquil streets of the British Capital.
