An American trio, from England via Australia. Barry Gibb and twins Maurice and Robin Gibb (brother Andy leveraged their fame into a teen idol career, cut short via rock star excess). They had already come and gone as a band, before settling in the US and ditching their ethereal pop for an R&B base, peaking with the Saturday Night Fever soundtrack, a dual phenomenon that made disco safe for (white, heterosexual) suburbia, much as Alan Freed and Dick Clark did for rock.
