I've seen that instrument before in Galicia, they call it zanfona
. I love how it sounds.
A good song featuring a zanfona is A Bruxa
as performed by Milladoiro on their album A Galicia de Maeloc
If you like celtic and medieval folk music, I heartily recommend to check them out.
Armisis: I wouldn't say Hurdy-Gurdy's are overpriced; the high-end ones are often real works of art, just like violins or fancy ocarinas. If I spent all that time crafting one by hand I'd charge someone a couple thousand for it too!
I'd say a zanfona is actually harder to make than a violin... there are a lot of mechanisms and moving parts involved.
