Alash Ensemble of Tuvan Throat Singers in Urbana

You could be forgiven if you’ve never heard of the tiny Central Asian republic of Tuva. There’s a slightly better possibility that you’ve heard of something called Tuvan throat singing, in which the singer can produce two, three, even sometimes four pitches at the same time. The Alash Ensemble, a band of master Tuvan throat singers and instrumentalists, will play in Urbana Sunday and Monday, and we’ll learn more on the Friday edition of “Live and Local.”
