Two Tons O' Fun, also known as The Weather Girls, was an American musical duo composed of Izora Armstead and Martha Wash. They rose to prominence in the late 1970s and early 1980s with a style rooted in R&B and disco, characterized by their powerful, gospel-inflected vocals. The duo is best known for their hit "It's Raining Men," which became an enduring dance anthem. Their influence has been significant within the dance and R&B genres, and they have been widely recognized for breaking barriers as plus-sized women in the music industry.
