The song was written by Peebles, her partner (and later husband) Don Bryant, and DJ Bernard "Bernie" Miller in 1973:
One evening in Memphis in 1973, soul singer Ann Peebles was meeting friends, including her partner, Hi Records staff writer Don Bryant, to go to a concert. Just as they were about to set off, the heavens opened and Peebles snapped: "I can't stand the rain." As a professional songwriter in constant need of new material, Bryant was used to plucking resonant phrases out of the air and he liked the idea of reacting against recent R&B hits that celebrated bad weather, such as the Dramatics' "In the Rain" and Love Unlimited's "Walkin' in the Rain with the One I Love". So he sat down at the piano and started riffing on the theme, weaving in ideas from Peebles and local DJ Bernie Miller. The song was finished that night and presented the next morning to Hi's studio maestro, Willie Mitchell, who used a brand new gadget, the electric timbale, to create the song's distinctive raindrop riff. It really was that easy. "We didn't go to the concert," Bryant remembers. "We forgot about the concert."
Ann Peebles said: "At first, we had the timbales all the way through the song but as we played the tape, Willie Mitchell said 'what about if the timbales were in front before anything else comes in?'. So we did that and when we listened back I said 'I love it, let's do that'." The organ is played by Charles Hodges, who later said: "We wanted to catch a sound like water dripping. Willie pulled the timbales out and Howard did the low part and Teenie did the high part. It was an overdub." Peebles said: "I have to give Teenie a lot of credit, because he added a lot of licks and details to make it right."
In 1978, Eruption released a disco-oriented remake which became the group's biggest hit. It reached the top 10 in many European charts, hitting the number 1 in Belgium for 2 weeks in March 1978. It was also a number 1 hit in Australia and reached the top 10 in New Zealand and South Africa. In the U.S., it peaked at number six on the disco chart and reached number 18 on the Billboard Hot 100.
In 1984 Tina Turner recorded "I Can't Stand the Rain" for her fifth solo album, Private Dancer, and released it as a single in early 1985 in Europe. Turner's version would find minor success in the UK, but would be a success in Germany, Austria and Switzerland.
