Budden is one of those people who know so much about a subject that you can only stand back and marvel. Now, if I knew a little bit more about this subject -- opera -- I might not be so struck, but I know just enough to appreciate the magnitude of his accomplishment. There's probably not another book on Verdi that you really need, and so far I haven't found one that is so well written. It's serious and enlightening and entertaining all at the same time. Budden is not a Verdi worshipper, at least not unreservedly. The operas in this volume span the "galley years" during which Verdi was honing his craft. He was working professionally, but he wasn't the master he would become later on. Budden lets us know in which ways Verdi tends to follow musical trends thoughtlessly, albeit intentionally, which young artists tend to do. And that's where biography comes in, so we get a little of that too.
I've been watching all of Verdi's operas in the Teatro Regio di Parma productions released as "Tutto Verdi: the Complete Operas" and reading Budden's commentary on each one. They help me hear things I would have missed after a first listen, and they're enriching my experience, even occasionally provoking a smile. Budden is never mean exactly, but he has a rather biting sense of humor. It's hard to write this engagingly on a technical subject without completely dumbing it down, but somehow he manages it.
