Era (styled as +eRa+, acronym for “Enminential Rythmn of the Ancestors”) is a New-Age music project by French composer Eric Lévi. They use lyrics (by Guy Protheroe) which, although similar to Greek or Latin, are, in fact, deliberately devoid of any exact meaning. Musically, the project blends Gregorian chants with modern elements and genres, especially rock, pop and electronic music. (Wikipedia) You can find more about the band on their official website.
