We call most of our current musical output Nu-Medieval music. It is not medieval music - it is modern music, for today. It uses many medieval and middle-eastern instruments and sounds, it uses some medieval musical theory (it is modal not harmony based) and it aims to take the listener elsewhere and elsewhen.
It is a soundtrack for those of us who have grown up with medieval-flavoured fantasy books, comics, games, TV series and films. It has echoes of history but it is music for now.
Secret Archives of the Vatican love genre-defying music, Dark Age primordial sounds, an ancient orient that never was, medieval echoes, dub, dubstep, DnB. Yes all of it!. Music that is sufficiently advanced is indistinguishable from magic!
