I wouldn’t file this in classical- although I can see why we mistakenly would. It has a dramatic movie soundtrack quality, soaring operatic primarily fem vocs, huge string arrangements. Electronic drums and chimes give it a pop feel in places. Very beautiful stuff from the Netherlands though it somehow seems Italian. If not general, file this under world, alongside Madredeus and other spooky lush female vocal centered exotic musics.

1) ave maria: restrained electrobeat under slow phrased operatic vocs + strings
2) upbeat pop rhythms but an exotic European feel
3) fem/male duet, tradicional epic folk pop feel, real drums
4) dark minor feel, cinematic operatic feel w/ many players-singers, ends a little early
