Even though their music has little in common with actual Gregorian chants, producer Frank Peterson's pop group Gregorian have managed to sell over five million records with their mixture of pop, esoteric ambient music, and chanted vocals.
After their somewhat darker album The Dark Side of the Chant, Masters of Chant: Chapter VIII returns to the successful formula of its predecessors, with covers of well-known pop hits such as Bruce Springsteen's "Streets of Philadelphia," Oasis' "Wonderwall," Bette Midler's "The Rose," U2's "Pride," the Killers' "Human," and the Bee Gees' "In the Morning.".
