It is one thing to be a virtuoso, but a different thing to play with compassion.

If you look at my collaborations, it is very much in line with all these others in the sense that it is a building of community, particularly among artists of color. This is what I learned from the example of elder African-American artists, which is where it is all coming from; to refuse to be silenced.

We think of music as this substance that flows - you turn on the tap, and there it is, streaming off your computer - but that's not how we evolved as a species. We evolved to listen to each other, and the reason we're able to listen to music in the terms is talking about is because we're really good at listening to each other. But this kind of technology has allowed us to forget that music is the sound of each other.

My concern with this approach is that music becomes a substance devoid of people. It's a consumer model of what music is: subjects listening to objects. For me, music is subjects listening to subjects. It's about intersubjectivity.

The sense of having to be the best at everything gets in the way of anybody doing anything. I put all that aside; it's not worth thinking about when I'm there. My agenda as an artist doesn't go away when I teach. It actually gets intensified.

What I've learned from my gurus is that when you hear music, you hear a person, or you hear people, and you hear everything about them in those moments. They reveal themselves in ways that cannot be revealed any other way, and it contains historical truths because of that. To me, that is the most important thing. It shouldn't be a footnote, or the last chapter. It should be the complete thesis about a book on listening.

In the 1990s I got to play in a group that played in prisons in California. We would play in maximum security wards. It was infuriating. Those kinds of situations stick with me. We got to come in and play music for them because that's a way of caring, just offering something, a gift, basically. They're basically the most grateful audiences I've ever experienced, because nobody's giving them anything.
