Three of R&B music's most beloved and consistently popular vocal groups. The Chi-Lites were formed in Chicago in 1959, originally called the Hi-Lites. The Whispers, began their legendary and timeless career in 1963. Their vocal style harkens back to a more genteel era of crooning, preferring soft pillow talk and songs that speak to heartfelt emotions. The Delfonics were one of the first groups to sing in the sleek, soulful style that became popularized as the "Philadelphia sound."
