In the 1980s, Joshua was active as a DJ and producer in the early days of the house music scene. His earliest productions were released on the Trax Records label. In the early 1990s, Joshua began producing remixes of songs by artists like Ce Ce Peniston, Malaika and many pop artists, including Michael Jackson. He continues to remix to this day.
Joshua is best known for his 1989 number one BillboardHot Dance Club Play chart hit "This Is Acid (A New Dance Craze)." The hit version of this song was a remix by UK DJ Les Adams, who pitted its spoken male vocals by "Hot Hands Hula" Malone against a combination of regional house music sounds of the day, including samples of sirens and sexual screaming voices in the background.
