Ever wonder what Vangelis did before he wrote that totally lame song from Chariots of Fire? Probably not, but he did have a satanic prog band of hairy Greek warlocks and pre-pubescent witches. Actually Aphrodite's Child started as a pretty run o' the mill hard psych band who released two sub-good albums. However, in 1972, after moving to Paris, Vangelis and his woolly coven recorded their meisterwerk. 666 is a massive conceptual double album based on The Book of Revelations, the bible's heaviest bit. Even though there is a strong occult vibe, and the subject matter is the Apocalypse, the material that makes up 666 is strangely upbeat and festive. Vangelis employed a myriad of instruments to meet the epic scope of his vision. 666 is easily one of the more satisfying ways to spend an hour, and I'm pretty sure the bible doesn't have any Hammond B3 or sitars in it.
