Bilingual edition (English/German)
In the AC, "alternating current", the new alternating exhibition area of Museum Ludwig called "Alternating Current", Isa Genzken and Wolfgang Tillmans are exhibiting together for the first time in a Cologne institute.

They both know each other well, Wolfgang Tillmans has already portrayed Isa Genzken several times. What is new, however, is how they observed each other at work and took pictures of each other. The tension with each other's handwriting is joined here by the examination of the other's way of working.
