In Enigma's fourth album, Screen Behind the Mirror (once called Mirror of the Moving World), producer Michael Cretu included Kamina Braria, a famous secular song collection in carl orff. Such a classic chorus combined with Enigma's powerful electronic synthesizer timbre has formed a collision between classical and modern, and the intersection of seriousness and fashion does not seem far-fetched. It can be said that the main theme of Bran's poems has become the most important musical pillar in Enigma 4, which runs through the whole record.
