I sing what I sing. And that's recitals and orchestra concerts. To appease - no, that's not the right word - let's say to satisfy - any opera urgings that my public has, I'll put in an aria.
In spirituals, the talk of heaven and deliverance was code for a better life. 'Crossing the River Jordan' was code, of course, for escaping to freedom.
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.
