The Mark of Cain

The Mark of Cain (also seen as the initialism TMOC) are an Australian rock band from Adelaide, South Australia. They released their first album, Battlesick, in 1989, following up with The Unclaimed Prize in 1991. Henry Rollins financed and produced their 1995 breakthrough album, Ill at Ease. A compilation album, Rock and Roll, was released in 1996 and The Complete Recordings 88–98 in 1998. These were followed by This Is This... in 2001 and Songs of the Third and Fifth in 2012. They have since undertaken several tours of Australia and played at several festivals.

The Mark of Cain were formed in mid-1984 by siblings Josie (Scott (guitar) and Kim Scott (bass), with Rod Archer on vocals and Gavin Atchison playing drums. In 1985, Archer left the group. Josie Scott took on the lead vocal role and the group has remained a trio ever since. The Scotts have been the core of the band, which has featured ten different drummers over the years, including former Helmet member John Stanier between 2001 and 2013. Eli Green stood in for Stanier from 2013 and is playing with them as of 2026. The band continues to write songs and rehearses together, with plans to release more songs.
