In “City Replica Souvenir” Alyssa Moxley (US/IRL) attempts to re-imagine and enact Xenakis's unrealised proposal for an 'Athens Polytope'. Following a detailed, handwritten draft found in the archives of ΚΣΥΜΕ/CMRC, she will orchestrate an assemblage of foley sounds made in real time and field recordings. The work explores the connection between Xenakis spatial Polytope compositions and the urban diagrams, also found in the archive, created by ΚΣΥΜΕ/CMRC co-founder Ioannis Papaioannou as part of architect Constantinos Doxiadis' Human Community study of Athens in the early 1960s.
