Album: Various artists, Moondust, (Heavenly)

The best ideas are usually the simplest, and Andrew Smith's quest to interview all the men who've walked on the Moon turned into an award-winning bestseller.

This is the accompanying soundtrack and many of its 21 tracks, which encompass psychedelia (Moby Grape, Grateful Dead), neo- classical (Ligeti, Herman) and singer-songwriters (Jeff Buckley, Richard Hawley), are literal, with lots of "Moon"-related titles. But the majority are chosen for their mood, making this a fine accompaniment to contemplating the cosmos.
