Every opera, because every opera is a unique slice of a particular perspective, historical perspective and psychological perspective if not musical style, and so forth, they all present different challenges. Some can be musically very challenging, some can be psychologically more challenging. There is always something that requires a pretty specific amount of energy and attention.

I think nervousness - a heightened sense of nerves and attention is a very healthy thing for a performer. It is an artificial environment that you are going into whether it's concert or recital, or stage. When I know something so well, I've done it so often, and you kind of walk out for Tuesday night's performance, or you feel like that, that makes me more nervous then being geared up. A little bit like race horses. In the same way that the horses are always difficult to get into that lineup, the worst time of my life is the 10 or 15 minutes before I go on stage.

I love to sleep because I need the rest, but I hate to miss something. I would love to be able to take a pill that I wouldn't have to sleep. So, sometimes what keeps me up at night is just that I don't want to say good-bye to that day. And at the same time, I love to start the next day. I think I'm essentially a very unsettled person.

I think one of the great things behind game theory, or game development, especially in education now, apropos, digital and new media, is finding a better, easier, more intuitive way to learn that takes that away from the drudge and the structured work part and puts it into the reflective, "I'm alive, I'm a human being, I'm not working right now," part. And I think that I would like to see music and arts and humanities become more able to even the color spectrum of the fan of activities.

The issues of poetry, and music, and dialogue with one another is the essential thrust of any song. The breakdown becomes the epoch, the language, the cultural tapestry from which it's echoing, if you will. I often say it's the eyes of the poet's and the ears of the composer's. This narration is what fascinates me endlessly.

Being a classical musician I'm fascinated with how my colleagues, not just singers, but every musician finds ways to express something else or something new or the same ol', same ol' in classical music. I'm always in dialogue with other musicians at least orally, if I can't be with them and a lot of dead musicians as well. I've learned a lot from dead people on recordings.

Once you go on stage you're essentially creating the world that people want to participate in. The worst thing you can do is go out on stage with the idea that you're going to communicate something you've learned and if you do it really well, they'll approve. If you go out in an approval process, you will be so nervous and so preoccupied you'll never get to the heart of what it is you want to make music with.
