Rhiannon Giddens is a rare talent.
here is your hurdy gurdy man
I realize there wasn't an actual hurdy gurdy , but I was just cranking you up a bit!I don't hear a hurdy gurdy though. False advertising! I thought there was some sitar, but according to wiki it's a tanpura, another Indian instrument.
Some of the folk metal bands use pretty much the entire arsenal. Bagpipes, accordion, hurdy-gurdy (if you've never heard of that, look it up; might be the weirdest instrument in existence) and pretty much anything and everything with strings. Lyrics can dip into folklore, legends, sagas, etc. The genre is a pretty interesting mashup. Here is but one example.
