Bananarama are an English girl group who had several hit pop and new wave songs in the 1980s. They have had ten singles in the top-ten of the UK singles chart to date, as well as three U.S. top-ten hits, one of which hit number one. Some of their biggest international hits include "Cruel Summer", "Venus", "Love in the First Degree" and "I Heard a Rumour". They are known for their unique vocal style which features all members singing the same notes in unison (rather than three-part harmonies). Lead vocals and background vocals were recorded in this way, and much of Bananarama's early material was recorded with all three members at the same microphone at the same time.
