The Bee Gees \nwere a musical group formed in 1958 by brothers Barry, Robin, and Maurice Gibb. The trio was especially successful in popular music in the late 1960s and early 1970s, and later as prominent performers in the disco music era in the mid-to-late 1970s. The group sang recognisable three-part tight harmonies: Robin's clear vibrato lead vocals were a hallmark of their earlier hits, while Barry's R&B falsetto became their signature sound during the mid-to-late 1970s and 1980s. The group wrote all their own original material, as well as writing and producing several major hits for other artists, and are regarded as one of the most important and influential acts in pop-music history. They have been referred to in the media as The Disco Kings, Britain's First Family of Harmony, and The Kings of Dance Music.
