Faith Hill & Tim McGraw

Faith Hill and Tim McGraw first sang together in 1996 on the duet "It's Your Love," which became a major country hit. They married that same year, and their partnership has been both personal and musical ever since. Their voices blend in a way that feels natural, whether on early tracks like "Just To Hear You Say That You Love Me" or later ones such as "Let's Make Love."

Both had established solo careers before they met. Hill started in Mississippi and briefly studied opera before turning to country, while McGraw came up playing in Louisiana honky-tonks. They've each released multiple albums on their own, but their duets have a particular warmth that comes from singing as a married couple. Songs like "I Need You" and "From This Moment On" carry that intimate, shared quality.

In 2017 they put out a collaborative album called "The Rest of Our Life," which mixed country with pop touches and did well commercially. They haven't recorded a huge number of duets together, but the ones they have, including "Keep Your Eyes On Me" and "Roll The Dice", tend to stick because they sound like two people who know each other's voices inside out.
