Some critisicm has been levered at this book for not covering many of the european elements of 'techno' ie. gabba, trance - but that would be the musical equivalent of expecting a critique of rock to include a discussion on the merits of steps, boyzone or abba. This book keeps to the key elements of the music and pays the due homage to Detroit that this city deserves as the spiritual home of techno (not forgetting the outstanding contribution of kraftwerk). It covers all the key aspects of techno that will influence its evolution in to the 21st century. Intelligent, interesting - excellent!
