Folk rock, before Bob Dylan 1965 Newport Music Festival played with an electric guitar, few people thought that rigorous and rational folk music would be combined with rock music. Folk rock draws lessons from the simple and direct melody of folk music and the strong beat of rock music, and expresses the philosophical theme of songs by more popular means. Folk singers have high requirements for the aesthetic value of music traditions, and Bob Dylan sings current affairs and politics in poetic language. The heyday of folk rock was very short. After 1965, the public lost interest because of the growing commercial atmosphere.
