Somewhat relatedly - I remember when P.J. Harvey started out, the press and Harvey, herself, always made clear the difference between P.J. Harvey, the three-piece band, and Polly Jean Harvey, the frontwoman. Then, as the scope of her albums expanded beyond that three-piece lineup, that distinction just seemed to fade.
She should release an album under the name "Polly Jean Harvey" and proclaim it her solo debut, as if all releases up until then were band efforts with a constantly shifting lineup.
