A few years ago I came across this book on the art of singing. A few pages in and I was hooked!! This book contains really useful and practical insight on the how-to's of singing, starting with the foundation of breath. It also really inspired my thinking to shift from "vocal instruction" to "whole musician" instruction, and is one of the foundational texts that led me to realizing that there is a world of self-discovery within the act of singing. I highly recommend you check it out!!!
