“There’s a challenge in trying to describe her voice. It’s the richness and the warmth and the depth just in the sound itself that’s so mesmerizing. But it’s not just the quality of the voice, it’s also her sensitivity and intention. It’s her use of text, the way she connects with language.

There’s something special about what she does that only she can do.”
