Child's career started when he formed an R&B-influenced pop rock band, Desmond Child & Rouge in 1975 with singers Myriam Valle, Maria Vidal, and Diana Grasselli, backed by hired musicians. The band was known for their inclusion on the soundtrack to "The Warriors" in 1979, with the song "Last of an Ancient Breed", and for the song "Our Love is Insane", which charted at #51 in the Billboard Hot 100. Their two albums received positive reviews but sold poorly and the group disbanded in 1980. One member, Maria Vidal, had a hit in 1985 with "Body Rock".
