In 1991, Scabbia began singing professionally as a touring musician for other bands and providing backing vocals. Later that year, she met the male vocalist Andrea Ferro and bass player Marco Coti Zelati of Lacuna Coil in Milan's Midnight club and started dating Marco after. At the time, the band was named Ethereal, and Scabbia was asked to do vocals by her then boyfriend and bass player, Marco. She was employed to record vocals on the demo tapes, and invited to be a permanent member. After several changes in the band's line-up, the members were reduced to Ferro, Coti Zelati and Scabbia. The members recorded a two track demo in May 1996, and were soon signed by the German branch of Century Media, eventually joining with the American branch of the label. Once signed, the band changed their name to Lacuna Coil after learning that a Greek band signed to Century Media had already claimed the name Ethereal. Adding new band members, Lacuna Coil began, releasing their first album in 1999.
