There's a description of Sparks in this book which sums them up perfectly: a Marmite band, in that you either love them or hate them. I fall into the former category - my girlfriend into the second, so I have to listen to their albums on headphones! - and absolutely adore almost everything they've done, so when I heard about this book I had to buy it.
The book looks great, a chunky hardback with three sets of black & white photos between within its pages, and the writing style is clear and easy to read (the author is a music journalist and a fan of the band). However, it must be stressed that this is an unauthorised biography and the Mael brothers did not participate in any way, so there are no new interviews with Ron & Russell, any quotes from them coming from old interviews. There are plenty of contributions from other band members past and present though, and support staff such as managers and record company executives. As with Sparks themselves, it is always entertaining, and I personally found it became more interesting as it went on, especially when their 1970s heyday had passed and they fell out of the limelight in the UK, releasing a string of cultishly popular albums in the USA for a decade or so, before they eventually returned to critical acclaim with the likes of "Li'l Beethoven". The book brings us right to the present too, also covering their most recent album, the radio musical "The Seduction of Ingmar Bergman", and at the end there is a discography, and a nice "what happened next?" where the current activities of many of the people mentioned in the book are detailed.
Any faults? After the detailed early chapters it does appear to become a little rushed, and rather than each chapter covering a single album as is the case in the earlier stages, towards the end there are some which cover up to three albums in a few pages. In addition, many of the chapters seem to mainly consist of a glorified review, where an album is mentioned, its critical reaction is outlined, and then the author delivers his own opinion where he picks his favourite tracks. These parts did feel slightly rushed, sketchy, and a little disappointing. I also found it surprising that there isn't an index.
On the whole it's a very worthwhile read for any serious Sparks fan, and I personally felt I learned a lot about them and their music. If you're not a fan this won't change your opinion, but if you are you'll find this a treat.
