Younger audiences probably know the Whispers from their 1987 super hit "Rock Steady," but this R&B vocal group has been racking up hits since the mid-1960s. We prefer their older material, which is creamed on a furlong of compilation albums showcasing their twin lead vocalists. The Scott brothers may have left the band in the early '90s, but the Whispers have carried on with class. They aren't really Quiet Storm, but they brew slowly boiling numbers that are perfect for car trips up to Inspiration Point.
