2018 collection from one of the most successful bands of the rock era. The Bee Gees formed in 1958. Their line-up consisted of brothers Barry, Robin and Maurice Gibb. The trio were successful for most of their decades of recording music, but they had two distinct periods of exceptional success; as a popular music act in the late 1960s and early 1970s, and as prominent performers of the disco music era in the mid-to-late 1970s. The group sang recognizable 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 Bee Gees wrote all of their own hits, as well as writing and producing several major hits for other artists. The Bee Gees have sold more than 220 million records worldwide, making them one of the world's best-selling music artists of all time. They were inducted into the Rock and Roll Hall of Fame in 1997. The Bee Gees' Hall of Fame citation says "Only Elvis Presley, the Beatles, Michael Jackson, Garth Brooks and Paul McCartney have outsold the Bee Gees."
