He became a famed mainstream/house producer and remixer by the 1990s, but Ralphi Rosario will forever be known as the author of house's most infectious hit, "You Used to Hold Me," as well as his status as a member of the illustrious Hot Mix 5 radio team that consistently lit up Chicago's WBMX during the 1980s with the best house tracks of the day. The Hot Mix 5 also had a record label, which released "You Used to Hold Me" as well as crucial Rosario follow-ups like "Pieces" and "I Want Your Love." He hit the dance charts consistently during the late '80s and '90s for labels including NiteGrooves, Henry St. and Jus' Trax. A 1994 re-release of "You Used to Hold Me" brought dozens of remixes, including Masters at Work, Danny Tenaglia, Hula & K. Fingers, DJ Hyperactive and Maurice Joshua. Rosario has himself remixed and produced for Pet Shop Boys, Gloria Estefan, Deee-Lite and Debbie Gibson. ~ John Bush
