Keith Caputo (born December 4, 1973) is best known as the singer of alternative metal group Life of Agony. He has also been active as a solo artist and has released several albums under his own name. In 1993, Life of Agony released their debut album, River Runs Red, and singer Caputo's expressive voice played an important part in its success. After five years and three albums, however, Caputo left the group to start a solo career in 1997. ~ Christian Genzel
