"Densely written and diligently researched, When Machines Play Chopin interweaves literary history, aesthetics, performance history, and the history of technology in new and unexpected ways. [...] By focusing on the literary life of music machines, Hirt presents a compelling narrative on music aesthetics and the mechanical from the eighteenth through the twentieth centuries, one with important consequences for a contemporary discussion of the place of the human vis-a-vis technologies of sound."Mary Helen Dupree in: Monatshefte 104/1 2012
