Deus Ex Machina, Cinque, temporary link only

 

This band is like the recent times' version of the classic Italian band Aera which it really feels like a perfect continuation of. There are very harsh dissonances, even harsher singing, all in latin of course, and really bizarre chords and melodies.  Sometimes it's successful but sometimes not.  It's hard to really enjoy the vocals.

Oddly enough the title doesn't represent the number of the albums, this is likely the 7th release. If you heard their previous ones, it's pretty much indistinguishable in my opinion.

Unusually for a prog band, they have their own wikipedia and allmusic pages.
