Yes, this group of Tuva throat-singers is unique. They are probably unlike anything else you have seen perform. The review by Rebecca Ostriker, in today's Boston Globe , comes close to putting the sounds they make into words we can understand.
I heard this group in July at the Lowell Folk Festival. They were outstanding. They created a mesmerizing sound and truly enchanted the audience.
If you get a chance to hear them perform, I think it would be a good thing to do.
