The most influential singer-songwriter of his era, Bob Dylan demonstrated that rock and roll lyrics, once known for their lightheartedness, could be rich, serious, and meaningful. Combining forms borrowed from folk ballad verse, blues, country and western, and gospel music and techniques gained from French symbolists and beat poets, Dylan revitalized the popular song and inspired other musicians to follow his lead in self-expression. Songs such as “Blowin' in the Wind” and “The Times They Are A-Changin'” endeared him to antiwar demonstrators and supporters of the Civil Rights Movement, and he was commonly referred to as the spokesman for his generation, a title he disavowed. As Dylan restlessly ventured from folk music to electrically amplified rock music to country music to gospel to blues to bluegrass, his audiences followed. In the course of a career that began professionally in 1961, Dylan has written more than three hundred songs, released more than forty albums, and performed live in more than two thousand concerts. Among his most celebrated songs are “Mr. Tambourine Man,” “Like a Rolling Stone,” “Subterranean Blues,” “Lay Lady Lay,” “Knockin' on Heaven's Door,” and “Tangled Up In Blue.” Dylan has garnered widespread praise for the literary merit of his lyrical compositions; his merits as a poet have been repeatedly compared to the likes of such literary giants as Walt Whitman, T. S. Eliot, and Allen Ginsberg. Dylan has received numerous honors and awards, including an Academy Award, and was named by Life magazine as one of the one hundred most important Americans of the 20th century.
