Loretta Lynn's younger sister Crystal Gayle built her own singing career on pop-friendly songs that made her a crossover star in the ‘70s and early ‘80s. Gayle's earliest efforts resembled her sister's traditional country material, but producer Allen Reynolds encouraged her to follow her own path; the honeyed, jazz-tinged delivery she adopted resulted in a slew of platinum-selling country hits that crossed over into Top 5 pop territory. Gayle's sultry image and cascading hair helped maintain her mainstream stardom into the early '90s, and she continues to tour and record.
