Bee Gees

The Bee Gees rank among the most commercially successful acts on this list, with over 220 million records sold worldwide. While their disco era defines much of their legacy, the Gibb brothers began as a rock act in 1958 on the Isle of Man before relocating to Queensland, Australia. Their songwriting genius produced timeless classics across genres for four decades. Notably, they are the only family group in history to have five consecutive number-one singles on the Billboard Hot 100, a rare feat in chart history.
