Tenores De Aterae to perform at St. John's Church in Williamstown on Friday

WILLIAMSTOWN -- Tenores De Aterae will perform at 8 p.m. on Friday, Nov. 30, at St. John's Church, 35 Park St.

Tenores de Aterae formed in Williamstown in 2008.

Their YouTube videos have gone viral in Sardinia, as they are the first non-natives to attempt the unusual cantu a tenore quartet vocal technique, which involves harmonic throat singing in parts. The effect often sounds more like instruments than human voice.

Sardinian song will be showcased.
