Vocals: Linda George, Sargon Gabriel, Juliana Jendo, Adwar Mousa, David Simon, Janan Sawa, Ogin Bet Samo
Not the best vocals, but decent artistry (which "saves" them): Evan Agassi, Ashur Bet Sargis, Geliana Esho
My personal favourites are Linda George, Evin Agassi and Ogin Bet Samo - Most of the Assyrian songs I have are by these people.
P.S. Linda George doesn't have kids and she is the only child, so the voice couldn't have "run through the family". Lol.
