Art rock

Art rock is a term used by some to describe art music based on rock music that is characterized by ambitious or avant-garde lyrical themes and/or melodic, harmonic, or rhythmic experimentation, often extending beyond standard modern popular music forms and genres, toward influences in jazz, classical, world music or the experimental avant-garde.

The concept of "art rock" has also sometimes been conflated with the "progressive rock" bands which attained mainstream popularity in the 1970s, but today the terms are usually used differently. Progressive rock eventually stuck as a label for a specific genre of rock music, while art rock remained a wider, more subjective and uncategorisable idea.
