The Sisters of Mercy are a dark, English rock institution with a vision sustained by frontman Andrew Eldritch and his beloved drum machine, Doktor Avalanche, for over four decades. Emerging from the underground in the early '80s, the group found mainstream success with a trio of influential releases (First and Last and Always [1985], Floodland [1987], and Vision Thing [1990]) that combined brooding industrial metal and art rock with opulent dance-pop and darkwave-influenced post-punk. Sisters of Mercy ceased being a recording entity in the early '90s but have continued as a live act into the 2020s with Eldritch at the helm.
