The Concrete Stereo, one of Arad's most important designs of the 1980s, is an iconic example of post-industrial aesthetics. With the realisation of electronics that were so small they no longer dictated the form of their housing, the production of home audio equipment became feasable, particularly as the parts could be bought as readymade elements. Arad chose concrete as the medium for this apocalyptic hifi, as a way of underlining its architectural character or to achieve a science-fiction look.
