These tiny 'Object Lessons', a range of books which are more like a long-form essay, explore often seemingly mundane items. ''Personal Stereo'' packs a lot of information into a small space. Split into three distinct sections: Novelty, Norm, and Nostalgia, 'Novelty' traces the origin of the Sony Walkman, from its conception by two Japanese business men to it becoming a recognised entity on the streets of America. 'Norm' follows on from the universal success of the personal stereo, relating this to the technology which it set the groundwork for, such as the ubiquitous proliferation of MP3s, the iPod, and Smartphones, leading to the eventual downfall in the popularity of the Walkman. Finally, in 'Nostalgia', Tuhus-Dubrow examines our need to hark back to a simpler time, when the personal stereo seemed the height of freedom.
