It's a nice idea, but we're far from convinced by Spinner's assertion that the new album art for PJ Harvey's White Chalk is inspired by Whistler:
Exhibit A: The dress. Exhibit B: The curly mane. Exhibit C: The titles of each project -- Harvey's 'White Chalk' vs. Whistler's 'The White Girl.'
So, yes, they both have a white dress, and some curly hair, but... erm, one is sitting with hands in lap, and one is standing with hands at the side; putting a woman in a simple white dress isn't an idea that Whistler can lay sole rights to.
On the other hand, if he were alive today, he'd probably be launching a lawsuit.
