Together with my friends and colleagues Caroline Haigh and John Dunkerley, I am the author of Classical Recording: A Practical Guide in the Decca Tradition, published by Focal Press. A labour of love for many years, it's been a delight to see it so well received, and to know that it's helping people across the world make better recordings.
If you'd like to buy it, I highly recommend getting it directly from the publisher. It's just as cheap or even cheaper than other online book stores, and we get more of the money!
