Corinne Bailey Rae is the new face on the scene. Her debut album a few years ago offered a couple of minor hits which deserve repeat listens. I believe she can be described as a singer-songwriter, as well, and the intimacy she must feel with her works adds depth to the music, I think.
I hate to describe her as an historical artifact, because by all estimations, Sade is timeless and transcendent. These songs from the Eighties certainly are. To call her a siren, a chanteuse, or a torch singer would be to minimize her sublime appeal.
