Boney M - Rivers of Babylon

Boney M. is a pop and disco group masterminded by West German record producer Frank Farian. They were most successful during the late 1970s.

The four original members of the band were Liz Mitchell, Marcia Barrett, Maizie Williams and Bobby Farrell.

Boney M., with their bubble-gum infectious tunes, became one of the few Western groups at that time to become well-known in places such as Africa, the Arab countries, Iran, Southeast Asia, and the Soviet Union. To this day, along with Swedish pop group ABBA, they are among the most widely known 1970s Western music acts in these regions.
