The Melbourne-based industry veteran got his start as a sound engineer in the mid-1970s. One of his earliest notable projects was producing the self-titled album for Perth glam-rockers Supernaut (3) before going on to work on The Ferrets' 1976 debut, Dreams Of A Love.
His renown began to grow and in 1978, he began what would blossom into a decades-long working relationship with Nick Cave, first by working on Door, Door, the debut album by The Birthday Party (then known as The Boys Next Door) before going on to engineer and produce their self-titled sophomore effort in 1980. He also worked with Nick Cave & The Bad Seeds on eight albums, beginning with 1984's seminal From Her To Eternity.
Other artists Cohen worked with over the years, included Models (2), Hunters & Collectors, The Go-Betweens, The Beasts Of Bourbon (and Tex Perkins), The Cruel Sea, TISM, Dave Graney, Kim Salmon And The Surrealists, Powderfinger, Paul Kelly (2), Blackeyed Susans, Mick Harvey, Kylie Minogue and Frenzal Rhomb.
He won three ARIAs in the mid-1990s — his first, in 1994, for Producer Of The Year thanks to his work on The Cruel Sea's The Honeymoon Is Over; his second two in 1995, for Producer Of The Year and Engineer Of The Year.
