Lacuna Coil is a Gothic Metal band from Milan, Italy formed in 1994. Formerly known as Sleep of Right and Ethereal, the band was inspired by gothic imagery and gothic metal music, and the members have been known, musically, for composing midtempo songs consisting of guitar lines overlaid with prominent keyboard work, and contrasting dual female/male vocal harmonies to help create a melodic detached sound.

Much of the band's recent material, however, sees a more down-tuned style, featuring a more distinct bass line and a higher mixing of the guitars within the songs. According to the band, they are and have been influenced by Paradise Lost, Tiamat, Anathema, Septic Flesh, Black Sabbath, Type O Negative, Imago Mortis, Depeche Mode, In Flames and Amorphis amongst others. The band's 2006 release, Karmacode peaked at number 28 on the Billboard 200. They have played among the world's biggest heavy metal festivals on the main stage including Ozzfest, Bloodstock Open Air, Wacken Open Air, and played with Megadeth on their Gigantour tour in November 2007.
