ID Plant - Flower?

Can anyone identify this - what I guess is a flower? It's on the new Fiona Apple cd cover and nobody has a clue what it is. You might get a better view on her actual website, but I'm including a direct link to the image as well:

Its an immature inflorescence of some monocot, probably an Amaryllid of some sort.
