Known for her distinctive and powerful voice, Wash first achieved fame as half of the Two Tons O' Fun, who sang backing vocals for the disco singer Sylvester including on his signature hit "You Make Me Feel". After gaining their own record deal, they released three consecutive commercially successful songs which all peaked at number two in the dance charts. The duo was renamed The Weather Girls in 1982 after they released the top-selling single "It's Raining Men", which brought them to mainstream pop attention. The Weather Girls released five albums and were heavily featured on Sylvester's albums. After disbanding in 1988, Wash transitioned to house music as a featured artist on several successful songs. Her success on Billboard's Dance chart has earned her the title The Queen of Clubland, with a total of fifteen number-one songs on the chart to date it is hard to argue with that description.
