Fog was composed throughout most of 2020, during the height of the COVID-19 pandemic. During this period, as a result of overwhelming stress from the pandemic, I struggled with brain fog (so terribly that I originally forgot how I composed this piece while orchestrating the initial sketches). Brain fog is described as a range of symptoms including forgetfulness, difficulty concentrating, and confusion. It is often caused by factors such as stress, lack of sleep, anxiety, and depression.
