Broomberg & Chanarin’s debut solo exhibition at Lisson Gallery consists of new photographic, moving image and performative works that collectively explore tensions between discipline and chance, precision and chaos, empathy and the involuntary pleasure of watching the pain of others. Central to the show is a new film work, Rudiments (2015) in which the artists have collaborated with a group of young army cadets at a military camp on the outskirts of Liverpool. Whether Broomberg & Chanarin have staged the scenes we observe or have simply documented the camp’s routine practice remains unclear. The young soldiers-in-training are seen marching, drumming and obeying instructions – enacting a collective, authoritarian form of obedience – with varying degrees of success.

The absurd and disturbing introduction of a ‘bouffon’ – a dark clown whose performance teeters on vulgarity – radically challenges the martial codes supposedly being taught and interrupts their carefully choreographed routines. The children also learn how to pratfall, ‘play dead’ or deliver convincing blows to one another, performing comic actions that are seemingly at odds with the hierarchical structures of the army. Broomberg & Chanarin’s film explores the experience of empathy or the enjoyment of pain in others through formative moments of childhood and innocence of early youth, as well as highlighting the importance of cadets to the armed services and especially the historical role of the drummer boy in battle. The work’s title refers to the 40 rudiments that form the technical foundation of percussive music – including rolls, strokes and paradiddles – while the soundtrack is propelled by a dramatic, improvised score devised for the drums by the American musician Kid Millions (also known as John Colpitts).

Accompanying the film are two large-scale photographic series, the first of which depicts bullets that have collided head-on and fused in mid-air. These improbable, perhaps even slapstick objects were originally found on the battlefields of the American Civil War and are said to have effectively saved the lives of two soldiers. For their second new series, Broomberg & Chanarin have photographed military grade prisms, shards of optical glass that are used in the sights of precision weaponry, but which also relate to the lenses found in the same photographic apparatus they use. Violence is transmitted through these materials: collided lumps of lead and the shear edges of crystal glass. The exhibition will also feature a live performance with two drummers, one snare drum, one chair, two clocks and a lead carpet, in which the drummers play a drum roll for the 6-week duration of the exhibition, without interruption.

The Lisson Gallery exhibition is an extension of a major show at the Centre for Contemporary Art Ujazdowski Castle in Warsaw (27 June – 6 September), who cocommissioned the film Rudiments with Forma Arts, supported by Arts Council England. This show coincides with the artists exhibiting as part of the eighth British Art Show (Leeds Art Gallery, 9 October – 10 January 2017, then touring to Edinburgh, Norwich and Southampton throughout 2016) and they will also be the next invited artists to exhibit and intervene within the Freud Museum in London (7 October – 22 November), exhibiting a new body of work, Every piece of dust on Freud's couch.
