While Test Pressing was on a couple of weeks back, photographer Christopher Fenner quietly took over one corner of a Hackney Wick community centre office. Setting up a makeshift studio of sorts, he made it his mission to snap portraits of artists as they went between the stages and visiting the green room to eat hummus. 

Over a 12-hour session, he produced a series of candid portraits of acts including Lust for Youth, K-X-P, Tiña, Martha Skye Murphy, PVA (above) and more. They happened either right before they played or just after.

The results are a collection of intimate images that mirror the energy and emotions of a day spent playing experimental electronic and rock music, ranging from the trepidation and steely calm of artists about to walk on to the highs that always comes after the noise.
