Is the first track on Peter Gabriel's 1986 solo album So. In the USA, it reached #3 on Billboard magazine's Mainstream Rock Tracks chart. Stewart Copeland from The Police played the hi-hat for the rain-like background sound; the rest of the drumming was handled by Jerry Marotta. The song is a combination of several inspirations. The lyrics directly reference a recurring dream Gabriel was having where he swam in his pool drinking cold red wine. Another version of the dream had bottles falling from a cliff, and the bottles were in the shape of people. When they were smashed on the ground, the people-shaped bottles had red liquid coming out, and then it began to rain the same red liquid. Earlier in his solo career, Gabriel had an idea for a movie, Mozo. In it, villagers were punished for their sins with a blood red rain. "Red Rain" was to be the theme song. This idea was eventually scrapped, although there was a mention of Mozo in the song "On the Air" in Peter Gabriel (II). "D! own The Dolce Vita", "Here Comes The Flood", "Exposure", and "Big Blue Ball" are also reference the Mozo story, as well. According to the sleeve notes from the remastered version of So, it is also a reference to acid rain. Based on one interpretation of some of the lyrics it is also thought to refer to nuclear fallout.
