While numerous tracks have become fan favorites over the years, the album saw considerably less success in Australia than previous releases and had limited exposure internationally. Apart from the psychedelic noise experiment "Travel By Thought", which prefigures the band's extended improvised tracks of the 1990s and beyond, all songs were written solely by Steve Kilbey.

The album marked the first occasion when group compositions dominated one of the band's releases. Steve Kilbey has said: "The demo situation was getting to us - me writing the songs on my eight-track and bringing them along to the band. It sounded too stiff. We'd reached this new energy level on stage which by far superseded anything we'd ever recorded, so we knew the only way to get sounding like that (on record) was for the whole band to write together."
