Not sure how I came across this book on Amazon but I thought it might interest a few of you folk on here, although not available until April 3rd I am sure it's going to be filled with a lot of useful info.
The price for the paperback version looks a bit steep, it may have something to do with the fact most people, like their music, don't buy physical copies of such things any more...
