It was only a short, exhaustively well-rehearsed and well-recorded step away to the Eagles and Ronstadt (and Asylum Records). Their careers proved central to those of surrounding singer-songwriters like Jackson Browne, Karla Bonoff, and Warren Zevon, whose simultaneous countryesque confessions creatively fed both the band and the singer. For Ronstadt, country rock progressively gave way to a wide variety of other styles, always approached from the point of view of her American sources, always mounted with the painstaking studio finesse exemplified by producer Peter Asher. For the Eagles, working first with the English producer Glyn Johns and later with Bill Szymczyk, the style became so full-blown that the band’s multimillion-selling album Hotel California (1976) both dramatized the Los Angeles milieu that underpinned the country-Hollywood connection and reflected the growing significance of the symbolism of country rock. Surrounding these careers were a number of other key figures. In addition to founding the influential Flying Burrito Brothers, Parsons introduced former folksinger Emmylou Harris to the music of George Jones, spawning her pursuit of a vernacular vocal art of operatic seriousness and intensity. Neil Young, formerly of Buffalo Springfield, began the traditionalist part of a gnarled, varied body of music that grew into a stylistic cosmos of genius unto itself. Like the Dillards, who came to country rock from a bluegrass background, all three chose not to work as commercially as the Eagles, Ronstadt, or Poco, whose driving force, Richie Furay, was another former member of Buffalo Springfield. Instead they preferred to have their music felt over time in ways less direct and less oriented to mass culture.
Country music often consists of ballads and dance tunes with generally simple forms, folk lyrics, and harmonies mostly accompanied by string instruments such as banjos, electric and acoustic guitars, steel guitars (such as pedal steels and dobros), and fiddles as well as harmonicas. Blues modes have been used extensively throughout its recorded history.
