All started in 1990 with same name album book MCMXC a.D. The thing made Enigma # -1 in most countries of civilized world - and why not, when the Earth was fighting evil to Bring Him Back to the Rivers of Belief. Others were with their ears in Sadness as the song was non-stop on all radium stations for 3 months ! Some even wanted to make MC pay them money via curt and law, shouting that their own music could be interesting to be sampled. Cretu didn't wasn't any samples, and decided it better to pay money.
