This book is a really interesting read, written by authors who clearly know what they are talking about, which is not always the case with books on music technology. It is, as the other reviews say, presented in a very readable, not too technical style. But I do have one or two quibbles. Firstly there is a slightly schizoid approach in this account; is it a book about Moog, or the development of the analog synthesiser? Yes Dr Bob was a key figure, but I felt that other actors, such as Pearlman or Zinoviev, got a more superficial treatment.
Then there are what appear to me to be some obvious factual errors. The one that had me scratching my head was the assertion that Pink Floyd used synthesisers on the album Meddle. This might sound a little pedantic, but as far as I can see the answer is no, they didn't. Sonically I hear no evidence of synths on this record and, whilst the sleeve notes are brief, to say the least, no mention of synthesisers. By contrast, the notes for Dark Side of the Moon make prominent reference to the VCS3.
Is this at all important? Well the thesis of the book is that the liminal status of the synth opened up a whole new world for musicians, which is largely true. But in other cases it did not. Delia Derbyshire, for example, never really took to the synthesiser. In the case of Pink Floyd it seems to me that their most experimental and innovative work (albeit the least commercial) ends with Dark Side, and the use of synthesis on later albums is a bit pedestrian. Ironically, the limitations of the Farfisa Compact Duo organ, the guitar techniques pioneered by Syd Barrett and the use of the Binson Echorec actually brought out a far more creative approach to sound.
As this book notes, synths, particularly those with presets, could actually make musicians lazy about the creation of sound. To use Brian Eno's word, the "easement" of constraints can actually deaden creativity; a fact that to some extent challenges this books account of the more or less unalloyed benefits of analog synthesisers.
