 With members who had been part of the cafe-based folk scene in Los Angeles, the Byrds adopted rock instrumentation, including drums and 12-string Rickenbacker guitars, which became a major element in the sound of the genre.Later that year Dylan adopted electric instruments, much to the outrage of many folk purists, with his "Like a Rolling Stone" becoming a US hit single.Folk rock particularly took off in California, where it led acts like the Mamas & the Papas and Crosby, Stills and Nash to move to electric instrumentation, and in New York, where it spawned performers including The Lovin' Spoonful and Simon and Garfunkel, with the latter's acoustic "The Sounds of Silence" (1965) being remixed with rock instruments to be the first of many hits.
