As well as his work with Queen, Mercury put out two solo albums and several singles. Although his solo work was not as commercially successful as most Queen albums, the two off-Queen albums and several of the singles debuted in the top 10 of the UK Music Charts. His first solo effort goes back to 1972 under the pseudonym Larry Lurex, when Trident Studios' house engineer Robin Geoffrey Cable was working in a musical project, at the time when Queen were recording their debut album; Cable enlisted Mercury to perform lead vocals on the songs "I Can Hear Music" and "Goin' Back", both were released together as a single in 1973. Eleven years later, Mercury contributed to the soundtrack for the restoration of the 1927 Fritz Lang film "Metropolis". "Love Kills" was written for the film by Giorgio Moroder in collaboration with Mercury, and produced by Moroder and Mack; in 1984 it debuted at the number 10 position in the UK Singles Chart. (A Richard "Wolfie" Wolf remix of the song was used as the end title theme for National Lampoon's "Loaded Weapon 1" in 1993.) Reinhold Mack also produced the 1987 single "Hold On", which Mercury recorded with actress Jo Dare for the German action drama "Zabou".
