"Strike It Up" was one of many high-energy hits of the early '90 with pulsating synths, verses by a male rapper, and a scorching chorus by female singer. The "Strike It Up" chorus is particularly hot, with the vocals by Martha Wash, formerly of The Weather Girls ("It's Raining Men
"). Wash was merely the voice of Black Box though; her part was played in the videos, on the cover art, and in live performance by a French model named Katrin Quinol, who didn't speak English.
Black Box is the creation of three Italian producers: Daniele Davoli, Mirko Limoni, and Valerio Semplici. According to Wash, they hired her to do demo vocals but then used those vocals on the actual songs, paying her just a flat fee for her demo sessions. She filed a lawsuit and ended up credited on the tracks.
Remarkably, this wasn't the only time Wash was misappropriated: She also sang uncredited on "(You're My One and Only) True Love" by Seduction and "Gonna Make You Sweat (Everybody Dance Now)
" by C+C Music Factory.
