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.

Blogging has mostly been an opportunity to react more immediately to experiences to try out ideas that I may end up using in the print media or in some other place. When I write books, it's a way for me to bring readers into the experience of writing the book, all through the process of writing the books that I write. I talk about what I'm up to in the blog. I let people know what I am doing. To me, it's just part of putting my professional life up in a way that people who are interested in it can access; and learning things from them as well.

The Armstrong record that I personally like the most, is a recording of a song by Harold Arlen called, "I Got a Right to Sing the Blues" . Most of Armstrong's solos tended to stick pretty close to the melody. But for some reason, it's like he let go of the tether and suddenly he's playing this beautiful high, almost abstract line that's floating above the beat. I compare it to the way that a 19th century operatic tenor might have sang an Aria because he's just completely let loose of the background and he's making this magic sort of flying above the staff.

The best of Donald Westlake's pseudonymous thrillers about Parker, the toughest burglar who ever lived. . . .Out of print for years and years, Butcher's Moon is the ultimate Parker novel, best read as an installment in the series as a whole but comprehensible and wholly satisfying on its own.

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

The most important thing to remember is that the composer is a senior partner. You cannot force a subject on a composer if it doesn't inspire him. He has to take the lead, you are an enabler, and you are creating the enabling conditions under which he can write great music. Your words are secondary. Many librettists in opera collaborations in the past have forgotten this, or not known it, or refuse to accept it and tried to get out in front of the creative process and it just doesn't work that way.

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.
