Crime & the City Solution were a rock group headed by Australian singer/songwriter Simon Bonney and active between the years of 1977-1991. Despite roots dating back as far as 1978, Crime & the City Solution did not truly emerge until 1984, coming to life in the wake of the dissolution of the seminal The Birthday Party. Crime & the City Solution had many members over the years, which can be divided into four distinct line-ups: Sydney in 1977-78, Melbourne in 1979, and two groupings in Berlin. The only common member in all four line-ups was Bonney. For a complete list of the different line-ups see below.
