Anyone interested in the mellotron and its use, from the early 60s to the present, will enjoy this huge book, which is quite good value at the cover price. However, it is poorly edited and full of grammatical errors. It is printed on rough paper (hence the modest price) such that the many black and white photos lack both sharpness and clarity.
Whilst the interviews with various musicians contain snippets of fascinating information, there is too much repetition of information about how the mellotron worked - I lost count of how many references were made to the fact that the instrument did not have tape loops but a single tape that allowed notes to be played continuously for 8 seconds before re-winding. Just one example of the poor editing is in the interview with John Hawkwen on page 306 where at the top of the page it is written "It was the Renaissance connection that did it for me with the Strawbs" and then five sentences later "..it was probably the Renaissance thing that clicked with the Strawbs".
The organization of the book is also unusual. At the start of the book only two pages are devoted to technical information and explanation about how the mellotron is constructed and works (out of about 600 pages in total) and this is followed by a section describing the musical context of the mellotron and the "progressive rock" genre.
Then, the interviews with various key musicianss are presented (although, sadly, Rick Wakeman is absent). These interviews are only partly about the mellotron, with a great deal of space devoted to childhood influences, early band experiences etc. The general consensus amongst these musicians seems to be that they loved the mellotron sound but didn't care too much for the instrument itself as it was too temperamental (especially when touring) and was little more that a large, cumbersome tape player.
Then there is an end section, in smaller font, which provides some more discussion about the "Golden age of the mellotron", "Ingredients for the golden age", "Musical traditions on both sides of the Atlantic divide" etc, followed by a useful section on additional sources of information.
In summary, this is a quirky book which gives the impression of having been compiled from the information researched, rather than written as a coherent and consistent narrative. Certainly, the beginning and end sections could have been combined in order to provide a more comprehensive perspective on this instrument that helped define the music of the 60s and 70s. Perhaps this will be done in a subsquent edition?
