In 1977, Brophy formed the experimental group → ↑ → more often written as Tsk Tsk Tsk or Tch Tch Tch, with Ralph Traviato, Alan Gaunt and Leigh Parkhill. Sometimes compared to Andy Warhol's Factory, the group produced experimental music, films, videos, and live theatrical performances exploring Brophy's aesthetic and cultural interests, often on a minimal budget. Over the ten years of the group's operation it involved over sixty of Brophy's friends and acquaintances including musician David Chesworth, and visual artistsMaria Kozic and Jayne Stevenson. They performed in a wide range of Australian venues including pubs, galleries, university campuses and the Clifton Hill Community Music Centre. They also performed or exhibited in Europe, including London's ICA. Brophy dissolved the group in the late 1980s, issuing a retrospective book "Made by → ↑ →", but continued to work with Kozic for some time. In 1980, he founded the Innocent Records label with fellow Melbourne musician David Chesworth. Throughout the early 1980s, Brophy wrote numerous compositions and multi-media pieces. In the late 1990s, Brophy founded the Sound Punch label, and released both solo works, and collaborations with Maria Kozic, Bill McDonald, and fellow RMIT academic Philip Samartzis.
