Keep it dark is one of those Genesis songs that at first seems quite simple. However, listen to the lyrics and you soon realize that the songt has many layers. Keep it dark provides an ironic twist. It describes a man abducted by Aliens and brought to an alternate world that is better than the one he lives in. When he gets back to the world he lives in, he decides to lie about the entire incident thinking no one would believe him. He explains his disappearance as a kidnapping that involved money. The twist for this song is that a lie is more believable than the truth.
