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. At the time, the band was named Ethereal, and Scabbia was first employed only as a session singer. She was employed to record backup vocals for the choruses of songs on their demo tape, but the band members liked the way the male and female vocals sounded together, and asked her 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 to tour, releasing their first album in 1997.
