Gregorian’s style traces back indirectly to the success of MCMXC a.D. by Enigma, created by producer Michael Cretu. That project popularized the use of sampled chant textures within electronic music, particularly in tracks like Sadeness Pt. 1.

Frank Peterson later refined the concept by replacing samples with real vocal ensembles, shaping Gregorian into a live-performance choral experience. The result was a series of albums under the Masters of Chant banner, where rock and pop classics were reimagined through orchestral vocal layering.

Gregorian’s catalog spans reinterpretations of artists such as Pink Floyd, Led Zeppelin, and Coldplay, reinforcing the project’s identity as a bridge between sacred soundscapes and mainstream music.

Among all their releases, The Sound of Silence remains their most viewed performance, followed by their rendition of Hallelujah, both demonstrating the enduring appeal of minimal melodies transformed through choral intensity.
