The winsome harmonies that brothers Barry, Robin and Maurice Gibb created as the Bee Gees are among the most addictive and recognizable in modern music. The UK-born trio resided in Australia, and their many contributions to the pop canon touched on varied musical styles—finger-snapping disco, lushly orchestrated soul balladry, sun-dappled Americana—enriching them with deft vocal interplay. Barry's falsetto helped tracks like the swaggering “Stayin' Alive” reach stratospheric heights, while Robin's dreamy lead on the gently rolling “Massachusetts” showcases his understated charm.
