A couple of factual errors I spotted:
Gilbert & Sullivan's "Princess Ida" was not a parody on Girton College, but on my own Alma Mata, Westfield College London. But that is probably a bit obscure nowadays.
He mentions the transformation of the Lute into the Electric guitar, and Mentions Jimi Hendrix... and James Brown. James Brown didn't play guitar. However since this book is 1999, and Jame sBrown didn't die until 2006, I suppose he could have learned, had he known about this.
And one other - which I forget - It was also related to popular music.
The error make me a little cautious - what else has he got wrong which I didn't know about? But generally a good stomping read, and coreect on the basic theses - the big transformations which changed music over the last 1,000 years.
