The Bee Gees were a British-Australian pop music group, formed in 1958, consisting of brothers Barry, Robin, and Maurice Gibb. Known for their falsetto harmonies, they are one of the world's best-selling music artists, with their signature sound playing a defining role in the disco music era of the mid to late 1970s. Their most influential work is arguably the soundtrack for the film "Saturday Night Fever", which included hits such as "Stayin' Alive" and "How Deep Is Your Love". The Bee Gees' distinctive fusion of pop, rock, and disco has left an indelible impact on the music industry.
