The first thing your eye does is climb. A gaunt, elongated figure stands to the left, poured into a dark full-body suit, one hand resting on a thin cane, the other raising a champagne flute toward his lips. His head is shaved close, his silhouette stretched to the very top of a doorway behind him. Beside him, considerably shorter and squarely planted, stands a bearded man with long hair in a pale button-up shirt and dark trousers, his hands open before him. Between them, at chest height, floats a small crystal ball catching the light. Everything is black, white, and shades of grey.

Those two men are the only members of Fleetwood Mac you see, and that is the whole point. The tall one is drummer Mick Fleetwood; the compact one is bassist John McVie. The band's two namesakes, its rhythm section, the pair whose surnames spell the name running across the top of the sleeve.

Why just them, and why that floating sphere held so deliberately between them? The answer is stranger than a simple portrait.
