Lacuna Coil, formerly known as Sleep of Right and Ethereal, is a metal band formed in Milan, Italy in 1994. The group consists of Cristina Scabbia (vocals), Andrea Ferro (vocals and keyboards), Cristiano Migliore (guitars), Marco Biazzi (guitars), Marco Coti Zelati (bass and keyboards), and Cristiano Mozzati (drums and percussion).
In 1994 Andrea Ferro and Marco Coti Zelati formed Sleep of Right, but soon changed their name to Ethereal, and signed to Century Media at the end of 1997. Finding that the name Ethereal was already taken by a Greek band, they changed their name to Lacuna Coil, which is half Italian, half English and translates to “empty spiral”.
