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 artists Maria 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.
Brophy dissolved the group in the late 1980s, issuing a retrospective book "Made by → ↑ →", but continued to work with Kozic for some time.
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.
Brophy has had works published in journals such as Virgin Press, Art & Text and Fast Forward and has presented papers at various film conferences since the early 1980s.
