As if they finally realized that they couldn't quite compete with contemporary musical fashions any more, the Bee Gees moved firmly into "mature" territory with Still Waters. However, they are canny enough to realize that they shouldn't abandon the frothy disco that made them superstars in the late '70s -- they should merely temper it with measured rhythms and tasteful melodies. Consequently, nothing on Still Waters is infectious, but it is pleasant, and while only a handful of singles stand out -- "I Could Not Love You More" is a sweet ballad -- it is still a fine, professional effort from these consummate professionals.
