Adasoffice in Switzerland made a remarkable design for “Who’s Johnny Cash?”, a multimedial and musical evening about Johnny Cash with Manuel Kuehne, Gisela Nyfeler, Adrian Perez, Florian Steiner, Christov Rolla & Miss Tigre and Tevfik Kuyas, Urs Müller and Arno Troxler, loosely based on Reinhard Kleist’s graphic novel Cash — I see a darkness.
