Izzo was an exacting perfectionist who drove herself hard, and the results show in One, which is a brilliant album still, full of her strong personality. Greg Kot called it one of the best singer-songwriter albums ever to come out of Chicago, and I concur. Izzo and Zas had faced a great deal of adversity—he received a kidney transplant a few years ago—and all their friends say they did so with great wisdom and strength. I'm told that toward the end, Izzo was in a great deal of pain and ready for release. Now it's the rest of us who will have to live with her loss, and a gap in the music world where her husky, fierce voice should have been.
