The 1960s and '70s are arguably country music's most interesting periods. As one generation of stars began to fade, new artists and styles appeared that reflected America's rapidly changing social culture. Sony Legacy's four-disc Box Set Series: Country Hits of the '60s & '70s offers a bevy of classic hits by a variety of artists throughout these two important decades. From the more pop-oriented sounds of crossover artists like Skeeter Davis ("End of the World") to the bluegrass sounds of Flatt & Scruggs ("The Ballad of Jed Clampett") to the iconic hits like Tammy Wynette's "Stand by Your Man" and Johnny Cash's "Ring of Fire," the '60s reflected a time of change for the country music industry. Several years later in the '70s, the outlaw country scene bloomed with Willie Nelson, Kris Kristofferson, and Waylon Jennings, while well-established icons like George Jones still recorded memorable hits. The 45 songs features on this box set cover the best of what the country industry had to offer during this time.
