From 27 April to 3 May 2015, Dresden will become a hotspot for advanced music and related arts as the ICAS – International Cities of Advanced Sound network reunites over 20 music and media art festivals into a Festival of Festivals. Assembling a mix of club concerts, outdoor interventions, a multi-day conference programme, a film series, lab formats, as well as an exhibition, the festival adopts the theme of “Tools for an Unknown Future” in an attempt to examine how to cope with increasing uncertainty using the tools that have been developed so far. In times with no illusions of utopia, the urge to find methods of self-empowerment – a back-up for the unknown – is more urgently needed than ever before.
