Among Dylan's many social protest songs are "Blowin' in the Wind" and "The Times They Are A-Changin'." Dylan's style evolved from acoustic folk (e.g., "Don't Think Twice") to folk rock (e.g., "Highway 61 Revisited"), country blues (e.g., "Country Pie"), and hard-driving rock. Enigmatic and reclusive, he became a cult figure; he has continued to tour and record new albums. Although many of his later recordings were not well received, his Time out of Mind (1997), Love and Theft (2001), and Modern Times (2006, Grammy) albums won nearly universal praise. He also wrote an early autobiography, Bob Dylan, Self-Portrait (1970); a late one, Chronicles: Volume One (2004); and a novel, Tarantula (1971, repr. 2004).
