Surrealistic Pillow and The Doors' Strange Days. These trends climaxed in the 1969 Woodstock festival, which saw performances by most of the major psychedelic acts, but by the end of the decade psychedelic rock was in retreat. The Jimi Hendrix Experience and Cream broke up and many surviving acts moved away from psychedelia into more back-to-basics "roots rock", the wider experimentation of progressive rock, or riff-laden heavy rock. Roots rock (late 1960s to early 1970s) Roots rock is the term now used to describe a move away from what some saw as the excesses of the psychedelic scene, to a more basic form of rock and roll that incorporated its original influences, particularly country and folk music, leading to the creation of country rock and Southern rock. In 1966 Bob Dylan went to Nashville to record the album Blonde on Blonde.

Other acts that followed the back-to-basics trend included the Californian-based Creedence Clearwater Revival, who mixed basic rock and roll with folk, country and blues, to be among the most successful and influential bands of the late 1960s.

The Byrds continued in the same vein, but Parsons left to be joined by another ex-Byrds member Chris Hillman in forming The Flying Burrito Brothers who helped establish the respectability and parameters of the genre, before Parsons departed to pursue a solo career. Country rock was particularly popular in the Californian music scene, where it was adopted by bands including Hearts and Flowers, Poco and New Riders of the Purple Sage, the Beau Brummels and the Nitty Gritty Dirt Band. Some performers also enjoyed a renaissance by adopting country sounds, including: the Everly Brothers; one-time teen idol Rick Nelson who became the frontman for the
