The Mark of Cain is a hard rock/alternative metal band from Adelaide, South Australia. Their style has been likened to that of Helmet and Rollins Band, yet this band predates both of those groups and was influenced by the early work of Joy Division and US hardcore. The Mark of Cain was formed in 1984 by brothers John (guitar) and Kim Scott (bass guitar), with Rod Archer on vocals and Roger Crisp playing drums. Before long, Archer had left the group and John Scott took on the vocal role; The Mark of Cain has remained a trio ever since.
