Dylan introduced a literary element to rock through his fascination with the Surrealists and the French Symbolists, and his immersion in the New York City art scene of the early 1960s. The trend of bands with names drawn from literature, such as the Doors, Steppenwolf and the Ides of March, were a further sign of rock music aligning itself with high culture. Dylan also led the way in blending rock with folk music styles. This was followed by folk rock groups such as the Byrds, who based their initial sound on that of the Beatles. In turn, the Byrds' vocal harmonies inspired those of Yes, and British folk rock bands like Fairport Convention, who emphasised instrumental virtuosity. Some of these artists, such as the Incredible String Band and Shirley and Dolly Collins, would prove influential through their use of instruments borrowed from world music and early music.
