Chuck Billy is an american singer, most known for being the lead vocalist of the thrash metal band Testament since 1986. Billy has remained constant as the vocalist alongside guitarist Eric Peterson who also was an all time permanent member. However, his vocal style has changed over the years from a clear thrash style to a death grunt. Since the Low album, he has mixed both styles and sometimes performs both on the same song.
