During its brief and stormy lifetime, Buffalo Springfield broke ground for what became country rock. In March of 1967, Buffalo Springfield went Top Ten with "For What It's Worth," written after the Sunset Strip riots. Not long after this success, the group began to disintegrate and ended up recording its second album on the run. Recording in Los Angeles was both exciting and enervating in the mid-1960s and allowed the group to work with some of the best available musicians from the area, among them Jim Messina. Neil Young was ambivalent about the group's fame, however, and eventually left the group to record on his own. Stephen Stills also left and formed Crosby, Stills and Nash with David Crosby from the Byrds and Graham Nash from the Hollies.
