In 2005 Corvus Corax started the ambitious project "Cantus Buranus": a full-length opera set to the original "Carmina Burana" manuscript lyrics. The music for the opera was fully composed by the band and had no connection with the famous work by Carl Orff. It was performed with symphonic orchestra, choir and medieval ensemble, combining traditional symphonism with medieval minstrel-like melodies. The project included a CD recording, a DVD, as well as live performances. A live CD and DVD recording of Cantus Buranus was released in March 2006.
