I've been indulging in a bit of Bulgarian throat singing lately. For twenty-odd years, ever since Kate Bush's album The Sensual World, I've gone through phases, though Ghost In The Shell inspired me this time round as I've been playing the score a lot in recent months (originally, the composer planned to use Bulgarian voices, hence the similarities). The 4AD re-release of Le Mystere Des Voix Bulgares is a good place to start if you aren't familiar. So powerful!
Also, I noticed two things going back over this thread just now:
My Call Of The Valley link is dead and someone mentioned the Talking Timbuktu album a few pages back but didn't post one. I wasn't familiar with the latter at the time, but have since become quite the fan following a rec from Phil Squaggers. African and bluesey - it's beautiful.
