Bang! is a compilation album by Frankie Goes to Hollywood given a Japan-only release during 1985. It is the first compilation album by the group, and the first to gather together various remixes that were difficult to find at the time. The album has subsequently become a collectors item in its own right.
For collectors, the inclusion of the Hibakusha mix of "Two Tribes" was a real find. This mix was originally released on the incredibly rare (limited to 5,000 copies) third 12", catalogue number X ZIP 1.
