If you read enough rock bios of one group or artist, you tend to become a bit punch-drunk. Several books about Brian Wilson and the Beach Boys are endless elaborations on a theme which could be summed up in two words: "Brian's weird". This book is like a breath of fresh air. Carlin has clearly been a BB nut ever since, as a schoolboy in 1976, he met Dennis Wilson by chance just before a BB concert, but this doesn't cloud his judgment one bit. For example, he describes the "MIU album" as "maybe one of the worst records ever made by a great rock band".
As Mick Brown did in the Spector bio "Tearing down the walls of sound", Carlin has dug back to his subject's schooldays more than any previous author I've read. Most of us have heard of the tyranny of Murry Wilson, but Carlin fills out the picture of how Brian dealt with it; for example, how he would often go to the house of his friend Robin Hood (!) on the major public holidays which, usually, "families tend to spend together". Carlin also gives Murry credit for his childhood role in protecting the rest of his family from his physically abusive father, Buddy (obviously a repeated pattern here).
Carlin makes the assertion - obvious when you think about it, but not all of us have - that Brian took to the Eugene Landy regimen so readily because he had grown up with a control freak (Murry) running his life, and was well used to the pattern.
There is a wealth of fascinating detail, e.g. the suggestion that "Caroline No" was originally "Carol, I know" (i.e. using Carol Mountain's actual name).
There is also a continuing analysis of Beach Boy politics, which started as an attempt by (particularly) Mike Love to get Brian back to writing hits ("don't **** with the formula") and ended with the bizarre three-way split we have today. Mike Love comes off fairly badly; for example, he is quoted as saying there was "a streak of insanity" in the Wilson family - which he is part of - and is seen backstage concealing the beer which he, as an avowed teetotaller, can't be seen to drink. (Perhaps Carlin should write a bio of Love - that would be a good read - but perhaps he doesn't fancy the lawsuits.)
But for a British fan, it is refreshing to read an American bio which recognises the British loyalty to the archetypal "American Band", and the importance of the British market to the group at times when, in their homeland, the Beach Boys couldn't catch a cold.
