Kenny Rogers may be best remembered for introducing a global pop audience to the homespun charms of country music. But his work as an ambassador didn't open just his listeners' ears: Perhaps more than any other Nashville act of his generation, Rogers, who died Friday at age 81, dabbled freely in other sounds and styles; his long and varied catalog, with its many collaborations, is a testament to both his musical curiosity and his keen commercial sense.
Looked back upon now, it also indicates clearly how country music, in many ways a hidebound genre before Rogers emerged, would evolve in his wake.
