Since then, there has been at least one Gregorian album release a year, so that the series has reached Chapter VI in 2007. It shows once more that there are no limits to Gregorian with songs from Coldplay to the Everly Brothers, from Björk to Queen and Lenny Kravitz. It’s not about music genres or a “hip” factor, the songs are the only thing that counts. Moreover, Gregorian has long become a music genre in itself.
Inspite of the Masters of Chant projects which regularly meet with theGregorian fans enthusiasm, the ever busy Peterson also takes his time for refreshing excursions. Gregorian’s The Dark Side, for example, was dedicated to hard rock songs from Nine Inch Nails, Sisters of Mercy, The Rasmus, The Doors and others. “For this album, we sent the older audience home so-to-speak and invited the younger generation,” laughs Peterson who is very well aware that there has never really been any generational conflict within the Gregorianaudience. Young and old are happily united at the numerous live concerts. Talking about live performances: by now, there are two live DVD releases and three DVD clip compilations which were recorded all over Europe and which show the impressive live shows of the ten classically trained singers in their monks’ costumes together with their full live band. The latest DVD was filmed in the medieval Kreuzenstein Castle near Vienna in autumn 2006 and was released in March 2007. Another outstanding special was released in November 2006 in the form of Christmas Chants which relied on the established originality of Gregorian and held its own against the flood of Christmas releases by easily entering the Top 30 of the German album charts at this difficult time in the market and it went on to become the most successful Christmas album of the year.
