From the outset, Test Dept were lauded for their innovative use of found objects, scrap metal and industrial detritus as instruments. The group's unique blend of aggressive percussion, noise, distorted samples and experimental soundscapes also reflected their commitment to challenging the status quo, most famously in 1984 when they ventured into the industrial communities of Britain to perform live with the South Wales Striking Miner’s Choir, raising money and awareness for that cause. Envisioning themselves as part of a broader cultural movement exploring the intersection of art and social change, their collaborative instinct led to the formation of The Ministry of Power, an umbrella organisation for working collectively on multidisciplinary projects that integrated music, movement, theatre, film and political activism. This led to large scale multi-media productions in disused industrial spaces and unusual environments. 2015 saw the publication of an extensive book entitled ‘Total State Machine’ that chronicled Test Dept's history, philosophy and work, while the ‘Disturbance’ album issued in 2019 incorporated expansive electronic production and was promoted with a tour. In 2023 the group was commissioned by the arts organisation A/POLITICAL to create the new large-scale work ‘Furnace' in an old iron foundry in southern France. This is an ongoing relationship that has further works in the pipeline.   2025 was a pivotal year as they linked-up with Canadian label Artoffact Records to commence an extensive back catalogue
