As stunning as it frequently is, the music of Dead Can Dance can also be downright silly. I mean, how "profound" can one possibly try to be? It's like we all need to be wearing cassocks and holding incense, in some 15th century cathedral. And I'm pretty sure most DCD fans rarely if ever set foot inside a church to hear choirs, madrigals, or have much interest in hearing indigenous music of non-western cultures. Instead, they'd rather the immaculately packaged fashionable European adaptation that 4AD, etc. exports for them.
Watching a show like Game of Thrones also has the effect of making much of DCD seem like background music for some fantasy show.
It's good to be somewhat suspicious of artists who take themselves as seriously as DCD must.
