>>126993180 (OP)Their later stuff has a lot to enjoy too. They stumbled a bit in the early 70s, got so soft they almost floated away, but Life in a Tin Can and Mr. Natural are very good albums from right before their big comeback (the latter's title track might actually be my favorite Bee Gees tune, sincerely), and the three disco era albums (four if you count Saturday Night Fever) also have their share of great songs, not just the singles. I also have a weak spot for Living Eyes, even though the band themselves hated it.
They weren't really a disco band, either. They had a lot of disco songs but their albums of that period are more varied blue-eyed sou and soft rock than straight disco and they were always a little miffed about being pigeonholed and their label always favoring the disco tracks.
