The British band Sade ruled the ’80s airwaves with a refined blend of sleek grooves and singer Sade Adu’s inimitable balmy purr. With hits plucked from across four platinum discs, this compilation is like a master class in sophisticated modern soul. “The Sweetest Taboo” showcases Adu’s supreme vocal prowess, all silken whispers and finely controlled belting, while “Smooth Operator” and “No Ordinary Love” show the band at their restrained best, with layered instrumentation and seamless production providing the springboard for Adu’s atmospheric croons.
