The film started as 40 minutes of shots of London during the first UK Covid 19 Lockdown (the strict phase of which began on 23 March 2020). These were taken on my phone during permitted exercise (cycling). The shots from 26 March are “imitated”. On the alto saxophone I have recreated and recorded as many as possible of the original sounds from the (poor-quality) audio on my phone-shots, and thus replaced the original audio. The shots from 28 March replace the original audio, too, but are “inverted”. I wanted to make a soundtrack that was in some definable way the OPPOSITE of the actual sounds recorded on my phone.
