Progressive country developed in the late '60s as a reaction to the increasingly polished and pop-oriented sound of mainstream, Nashville-based country. Inspired equally by the spare, twangy, hard-driving sound of Bakersfield country, the singer-songwriter introspection of Bob Dylan, classic honky tonk and rock & roll, progressive country was the first anti-Nashville movement to emerge since the dawn of rock & roll. Progressive country was rootsier and more intellectual than many of its contemporary genres; it was more concerned with breaking boundaries than with scoring hits. The genre was also songwriter-based. Many of its key artists -- Kris Kristofferson, Willie Nelson, Billy Joe Shaver, Tom T.
