As the Beatles represent the most important English contribution to rock in the 1960's, Bob Dylan is the most important American contributor. It is true in spite of the fact that he has never reached the top sale list of the record industry in the way the Beatles have.
Bob Dylan emerged from the popular folk movement during 1962 and 1963. His first two records, “Bob Dylan” and “the Freewheelin' Bob Dylan”, appeared in those years and established his national reputation. This reputation grew slowly, and was helped by his appearance around New York City and at college concerts. As early as 1962, Dylan became known for the quality and quantity of his song-writing. And Dylan's material has reflected a social awareness and has always involved protest against injustice. It has aroused a broad trend of similar songs in the present-day market. These elements, in combination with Dylan's particular sound, have made him one of the most remarkable figures in the history of rock.
