On subsequent tours throughout 1965 and 1966, his electric sets (now backed by The Hawks) were often met with derisiveness from the audience. Crowds became particularly acrimonious during a British tour, including an oft-cited incident in Manchester, where a member of the crowd shouted "Judas!" at Dylan; shows from this tour have been documented in several Dylan documentaries including 2005's "No Direction Home". Over time, Dylan continued to evolve musically, turning to country music on "Nashville Skyline" (April 1969), and drifting through numerous styles throughout the rest of his career. Over time, his electric period has since come to be recognized by critics and fans as producing some of his best-received music, and his controversial performance at Newport has been considered a pivotal moment in the development of folk rock.
