I'm not a lifelong Dead Can Dance fan, but I've been listening to some of their music recently. It's engaging and provocative. I felt something similar the first time I started getting into Nick Drake. The music is completely different, obviously, but it has that same quality of being able to stir up a range of emotions in a listener. The albums I have been listening to are more than 20 years old, but you wouldn't know it.
The video to the piece "The Host Of Seraphim" is powerful. Perhaps it won't be to everyone's taste, but watch it and tell me what you think.

For one of the most amazing pieces of music ever, you should check out 'Cantara' by DCD. It's on YouTube live from a concert in LA. Sadly DCD disbanded a few years ago, but most of their albums are in a class of their own.
