I bring my classical training - some of it, but not all of it - and also my background and culture, to spirituals. And I try to leave room for that unpredictable factor, where the feeling of the song is allowed to come through. The same ethos can be applied to singing Mozart, or Schubert, or Bach. It's not just about what's on the page.

I hear music that comes out of need, out of grief, sorrow, suffering and out of overcoming these things, as well. That journey to freedom still goes on today. It's an incremental change, the culmination of many events in your own life and the lives of your children and grandchildren.

New York is a great place to be fed in the arts. The arts in general are a large part of my life. The city was my postgraduate course.
