Bolex Dementia is the second and final album by the 1970s British rock band Hard Stuff. During the recording of the album, two members of the band (John Cann and Paul Hammond), were injured in a serious car accident in Belgium. Cann had been sitting in the front passenger seat of their Ford Zodiac and suffered an injured back and broken ribs, while Hammond, who had been asleep in the back seat, broke both his legs. Cann spent a week in hospital in Ostend, and Hammond two months.
