Gregorian

One of the most successful pop/classical fusion projects, Gregorian mixes well-known pop and rock songs with Gregorian chants. Overseen by producer Frank Peterson, co-founder of Michael Cretu's Enigma outfit, Gregorian's first album, Masters of Chant, released in 1999, became a smash hit throughout Europe, entering the Top Ten in nine different countries. The following albums continued in the same vein, covering songs by Peter Gabriel, Lenny Kravitz, Coldplay, Björk, Queen, Tears for Fears, and others. A 2006 album, Gregorian Christmas Chants, sold over four million copies.
