Black Box was an Italian house music group popular in the late 1980s and early 1990s. The members of the group included a trio made up of a club DJ (Daniele Davoli), a classically trained clarinet teacher (Valerio Semplici), and a keyboard and electronic music "wiz" (Mirko Limoni). The three had previously joined to form a group called Groove Groove Melody, producing dance music under names such as Starlight (who had a UK Top 10 hit in August 1989 with "Numero Uno") and Wood Allen. They went on to record music under many other aliases, most notably the alias Mixmaster, which scored a UK #9 hit in November 1989 with the song "Grand Piano".
