The Sisters of Mercy are an English rock band that formed in 1980. After achieving early underground fame in UK, the band had their commercial breakthrough in mid-1980s and sustained it until the early 1990s, when they stopped releasing new recorded output in protest against their record company. Currently, the band is a touring outfit only. The group has released three original studio albums, of which the last was released in 1990. Each album was recorded by a different line-up; singer and songwriter Andrew Eldritch and the drum machines called Doktor Avalanche are the only points of continuity among the line-ups. Eldritch and Avalanche were also involved in The Sisterhood, a side-project connected with Eldritch's dispute with former members. The group ceased recording activity in 1993, when they went on strike against their record company Time Warner, which they accused of withholding royalties and of incompetence. Although Time Warner eventually let the band go in 1997, they have not signed to another label, and have chosen not to use an independent label, despite showcasing numerous new songs in their live sets.
