A spectre is haunting central London, the spectre of five ebullient young men podcasting outside a pub on a warm night - the occasion is Olaf Nicolai’s Marx, a 24 hour film shown at the ICA this week, which consists entirely of one continuous closely-framed shot of a Karl Marx statue in Chemnitz, Germany. Owen and Ralph are joined by Daniel Neofetou, Matthew Turner and on the phone from Munich, George MacBeth.
