The Berlin-based artist Christopher Rollen uses art as cartography, a mapping out of experience that is past, present and passing away. A couple of years ago in northern Cyprus the artist came across a 1960s Turkish vinyl pop record. Here he presents Toprak, a video reverie in which the disc’s surface damage is amplified to evoke the country’s distressed history. The central installation, however, is the audio-visual archive Doegen Revisited (pictured). The piece pays tribute to the work of Dr Wilhelm Doegen, who accumulated an early 20th-century library of 1,650 shellac recordings of the Personalbogen (speaker data) of prisoners in 70 different war camps.
