Enigma is a German musical project founded in 1990 by Romanian-German musician and producer Michael Cretu. Cretu had released several solo records, collaborated with various artists, and produced albums for his then-wife, German pop singer Sandra, before he conceived the idea of a new-age, worldbeat project. He recorded the first Enigma studio album, MCMXC a.D. (1990), with contributions from David Fairstein and Frank Peterson. The album remains Enigma’s biggest, helped by the international hit single, “Sadeness (Part I)”, which sold 12 million units alone. According to Cretu, the inspiration for the creation of the project came from his desire to make a kind of music that did not obey “the old rules and habits” and presented a new form of artistic expression with mystic and experimental components.
