I was really impressed with the online chapters.
My copy arrived the other day, and it is great. Aesthetically a very pleasing book too.
Managed to find a brand new copy of Curtis Road’s Microsound a couple of weeks ago. Very much looking forward to getting stuck into that.
Definitely recommend Unlocking the Groove.
Also, not about music, but Sonic Wonderland: A Scientific Odyssey of Sound by Trevor Cox is a lovely book about a career in field recording.
