Vocalist Billie Holiday was born 100 years ago this week. Today, her place in music history is clear.
"I think we witness in Billie Holiday's music the beginning of the jazz vocal age, really," fellow vocalist Cassandra Wilson says. "Her phrasing is very conversational, and it swings — it moves with the musicians. She's very much in charge of her place in the music. She's in control of the story, and in control of her cadence."
