When Hot Mix 5 was formed in 1981 on radio station WBMX (now WVAZ), Rosario, the youngest member of the group, was still in high school. The Hot Mix 5 went on to become one of the leading forces in the early Chicago house music scene.
Like other members of the group, Rosario eventually branched out into music production and remixing. His first release, made in collaboration with Vince Lawrence, was "Sample That!" in 1986 under the name Bang Orchestra. In 1987, his collaboration with Xaviera Gold, "You Used to Hold Me", became a big hit for Rosario that was subsequently remixed and re-released several times.
