Oh no, it's THAT question... How am I going to answer it now? "Everything" is not exactly true. But then again, I love trying anything.
Out of your selection I have to second josediccus, and say Bongeziwe Mabandla was the best, though FloruitShow was a close second, even though they are completely different. Reading your description I was certain I would like Waldruna, but right now that wasn't the case. A bit too slow and meditative for this moment, though I can see myself learning to love it later on.
Regarding my taste of music, I've been trying to define it for as long as I can remember, lastly in my Monday Music blog series. After 50+ posts I still don't feel like I'm getting any closer. Take a look, I'd be curious what you think.
