The Sisters of Mercy are an English rock band formed in Leeds in 1980. After achieving early underground fame there, the band had their commercial breakthrough in the mid-1980s and sustained it until the early 1990s, when they stopped releasing new records in protest against their record company, WEA. Currently, although the band are a touring outfit only, they continue to perform new and unreleased music live.
