That's something you can't get off the wires in New York is people providing intelligent coverage of what your theater company in Podunk is up to. Many of the people who write what we call amateur criticism are professionals in anything other than name and receiving a paycheck. Very often, they know more than the professional critic who might be writing for their local newspaper. So, really, I'm all for it. It's changing the playing field, it's shaking things up, it's going to make the critical environment a healthier environment.

This impeccably researched study of the classic black insult game may be the funniest work of serious scholarship ever published.

I was interested in Armstrong to begin with because he is the most important figure in Jazz in the 20th Century. There's simply no question about it. I mean, if you're going to compare him to somebody, it's Shakespeare in terms of centrality of the tradition, in being at the beginning of it.

The problem with the Jude Law "Hamlet" was simply that it wasn't unpredictable, that it was a very down-the-center modern production. You wouldn't go to the theater expecting to see an old-fashioned "Hamlet" where everybody wears an old fashioned costume. You don't get points for putting on a "Hamlet" where everybody dresses in black. I've seen that one several times. But again, it's not that it has to be new, it simply that it has to be different, fresh, that it doesn't bore, that it doesn't make me - I don't feel as I'm watching it that I know where it's going to go.

It's actually now, more common to see conceptual productions of Shakespearian, which Hamlet is played as a Nazi, or a homosexual, or whatever concept is being laid over the play, then it is to see a production of Shakespeare in which there is no conceptual overlay and the play is simply being presented on its own terms.

I had a checklist in my mind of the things that make a biography practical. Is the source material centralized? Is it easy to find? Are there new primary sources that no one has ever had access to? Are all the sources in English? If they're not, are they in a language that you speak? And I realized that not only is Armstrong the most important figure of Jazz in the 20th Century, but he's a perfect subject for a biography for all of these reasons. I had always loved his music and I had been fascinated in him as a personality. And that's really the key to writing a biography.

I've always loved opera; it never occurred to me that I would write a proper libretto. One of my closest friends is a composer, Paul Moravec, and a few years ago, Paul and I were at lunch, and I said to him, "you really have to write an opera." So, he says very casually to me, "I'll do it if you write the libretto." Well, little did I know that the within a couple of years we would end up getting a commission from the Santa Fe Opera to write an opera together, "The Letter," which turned out to be the most successful commissioned opera in the history of the Santa Fe Opera.
